I can see how that might be helpful to some of them... we are kind of stuck with a lot of catch 22
Writing a manual is nearly impossible as by the time its done, things have changed rendering the manual, almost obsolete. It takes for a Tehcnical manual, for say, In my own experience my "D-Star" manual, takes a 4-5 hour conversation with a person to about 100 pages. Took me over 2 months to complete, revise, spell check, graphics, flow testing, first readers, repeat. Something as complex as plane shift, I'm guessing with access to all of the "Secret" data, I'm guessing 3-4 months, before the first vision of it would hit the web, already since I been here, they have added music, and magic resistance.
Would I love to have an accurate manual of all of the game commands, all of the procedures on how to do this and do that, and all of the gaming controls, or how difficult which monster was to kill, so i could gage my progress that way? Oh heck yeah. I'd even print it out and put it in a three ring binder every new version and it would probably be thumbed silly by the time the new version came out.
But thats just me, I'm the techno geek, give me data, procedures specifications, and turn me loose.
The problem you run into with a "Booth" is one keeping all that info current takes almost a small army. Look at the responses for the games official wiki. Let alone why stop to read a bunch of books when people around you are throwing spells, wandering around and having conversations. But it does give me an idea. What about a main tunnel. It would have to be up to the DEV when they redo Hydlaa's map again. Guilds could set up booths (those with guild houses) along either side of it for people new to the game that are interested in, the In game and out of game information about the different guilds. It could be literally be a tunnel from the higher levels. Drop an NPC there to be the newbie helper to point out once again basics, website, forums, wiki and the guilds.
That way with the booths, guilds can leave say an guild email address to handle people OOC who are interested in setting up an in game meeting with a character to work it out. For one it would give us guild folks access to an email address we can send basic 'set up you chat to this' 'right click the white diamond to show the guild icons' etc those kind of directions, and thus for guild newsletters what ever that particular guild needed/wanted. And secondly Give IC information about the guild and OOC information, thus Evil characters can go to Evil guilds etc. It also might help smaller guilds who are looking for new members too.
