I must concede that I, too, fin the statement "tester first, player second" to be a bit misleading.
I think that it is supposed to mean that
- when there's a bug or some other problem, we are
expected to check if it is known, and if not, report it.
- we are allowed to make use of the implementation if possible, even if it is not really IC; however, shall avoid it when currently in some RP, i.e., do it more or less privately
- we are expected to not be annoyed if the game acts up, and to know about, understand and accept the side-effects of testing, including: lack of implementation, severe breakage, server crashes, unannounced changes in behaviour, prolonged outages of parts of or the entire system, wipes, frequent and huge updates, unfinishedness of every sort, etc..
However, it does
not mean that we're supposed to RP only when there's nothing else to do. It has been stated several times that we are expected to play the game
as if it was finished, which includes to RP, to not exploit bugs, to not abuse the system, etc., because only this way the game can be tested properly (i.e., by simulating the final environment to it).
Obviously, the development state PS is in will force playtesters into full tester mode more often than a semi-finished game, but that's not to be confused with purely OOC testing.
The way you decide to start your PS experience depends on you, to some extent. You are expected to have read up on at least the major parts, like the overall background ("History" section on the main site). Also, you are expected to be familiar with the controls, at least in theory, by having read the player's guide.
The game
does have a tutoring mode (the figure with exclamation mark that'll appear whenever you do something new for the first time) It is limited, but also tells things one may not know yet.
You are further expected to be in general agreement with PS's mindset (notably RP-basedness) and proper netiquette.
Whether you choose to first get comfourtable with the controls, possibly customising them, explore the major elements of the game and parts of the world and only
then start to interact with others, or make contact even with only theoretical knowledge, thereby possibly having the additional enjoyment of exploring in company, is up to you.
I don't think that actively avoiding people is necessary if you have read up on the background first, especially since there's little additional general information to be found ingame.
However, it is preferred to have at least a basic idea of the character that you are playing (general personality / mindset), so that you can meaningfully interact with other characters.
Regarding MB: I found the crystal hunt horrible for it's utter OOC-ness. The lengths people went to in order to "win" a completely use- and mindless game showed some of the reasons why the RL world is the way it is, and served to highlight / prove necessity of some of the strict rules that PS finally has and will have. Insofar, it was, well,
educating, but that's more or less all the good that can be said about it, and I'm glad it's gone. Yes, starting CB with a fighting system wasn't much better, but I'm not going to re-state the obvious.
@themule: One of the problems of undesignated OOC is that it is by far not always possible to infer the context from the text, and things can get very confusing. The reason is that, unlike in a P&P RPG, you have
no means of interaction with the other player other than the text and video, none of them can show you actions, body language, or any other clues of what the other might be referring to. While "My computer is so slow!" clearly is OOC, how about "I have _no_ idea why I'm even putting up with you!"? Add to that the limited space, the long time it takes to type/read, and the possibility of lost / overlooked messages, and you'll easily see why undesignated OOC can easily lead to disruption. Now, even if the conversation were to stay nice and friendly, imagine what happens in a case of one player thinking it is IC and the other thinking it is OOC for an extended period, like an hour? For one, the RP will be completely invalid, and if the player intended to RP, then they may very well become frustrated upon finding out. Likewise, the OOC-er may easily be frustrated by realising that they've been socialising with something nonexistant (a virtual character in a game).
Then also add that in order to infer OOC-ness from the content, you must first have read at least part of the sentence, while with brackets you can skip it immediately, which in turn leaves you with more time to focus on the IC conversation (and vice-versa).
Last but not least it serves as a constant reminder that IC is encouraged and OOC is, at best,
endured.
support 1280 x 960 please!
It does already. In fact, it supports more or less any resolution you could possibly want, and a lot of resolutions that you certainly
don't want on top of that (like the 1280 x 96 that I once accidently set it to

)!
Simply run the setup application (pssetup), select "other" (or whatever it's called) and enter the desired resolution there.
However, know that your name "Demon Lord" is
not in accordance with the naming policy and will therefore get reported if you used if for your character.
