In fact, I hope every one of them will come to that point eventually, it's just not my "role" to force my current RP conditions on them... or on anyone else, for that matter.
Many do in their own form
And/...you don't have to.
But. you can let them know how you feel, or the course of game play that you have decided to take. Which you did here. Some you may have to tell in-game because they do not come here.
Keeping in mind that some of the people that helped you out may also be rather new to the game and like you they are trying to make their place and to make friends that they can play with. Finding the right group for a character to fit in sometimes can take awhile.
Patience is a good practice. Someone was with you once. I would suggest that you respond to the /tells in a RP fashion if you don't want to say that it offends you outright. The practice becomes habit forming even to those that you respond to because it sets a pattern in the manner that you would like to be addressed with. Many will adjust their texts by your example, for some it takes time. It still works for them as well.
Letting them know you are engaged in a RP, and that you will talk to them later is also a good and subtle hint. Many players will give you the respect of not bothering you as you are obviously busy. Most of the players I send tells to I simply say hello, and ask if they have a moment. I can judge by their response time if they are usually busy or not, or they inform me that they are and I try to catch them at a better time, or they will get back to me.
If it is a longer drawn out conversation. a short group may help, and let your explain your viewpoint better. Either way you will need to let those who you befriended that you are upping your standards and that you wish for it to be a standard practice with you.
That's where the misunderstanding starts, IMHO. To participate in events one must either be a RPer already, or be very sure of his/her own ability to learn RPing realtime, on the spot, in Main, with the risk of ruining it for other players if it all goes wrong. There's more than just me not fitting into any of these two slots.
Not true
My character is a ruff and tumble type of guy. (He is a grinder type if you will) Which is how he presents himself. There are a few friends that I struggle with in RP's. Because they are very good and make me feel way out in the outfield sometimes. I learned to let my character be himself. I don't bend him to their fashion and they don't bend for mine. Which makes it more realistic in the conversation. It also provides a certain awkwardness in the meeting that would be present due to the differences in the chosen lifestyles.
Participating in a RP event and ruining it for others is unlikely to happen unless you run around with the intention to disrupt it. Experienced characters will see you struggling and will at most times lead you into the flow of the RP if it has an established direction. Many do not and they will just go with what is provided. Needless to say RPers are not as stand offish as many think they are. As I see that at least one in this thread has offered their help. You will find others in the Rpers post to meet other RPers thread.
RP happens everywhere if you look. No it's not always the best but it is an attempt by most. Newer characters not with standing. Then again they are just learning. and you can teach without preaching by simply finding a way to to direct their questions by staying in character. Some will not take the hint and need grouped or the use of tells to get them from disrupting main while they learn. If you can't or don't have the time ignore them or ask someone who you know is willing to help help them. If you do not want the excessive random tells feel free to direct them my way. I'll take them under wing until they find their niche, or I can direct them to those of similar interests.
If you see an event posted here that you would like to join into. I am sure those involved would welcome you as they wouldn't post it if they didn't. If you are uncomfortable about sending them a [Hello, I am So and so, I would like to meet your character so I can join in your RP] then you can possibly contact them here by PM or by posting in their thread of your interest.
As far as RP goes in my book you make your own most of the time. Just take a moment to say hello to people as you meet them and doing so as you would walking into a RP, I think you will find many will engage with you in conversation in like manner. Something more in depth you will have to look for again I direct you to the RP event thread and get used to the names there. then try to randomly meet those characters in-game.
Taxing Tells
I don't think that is necessary and is a useful tool the way it stands. And a great one that can be used to direct some of the silliness out of the main chat, as well as giving quick directions and/or assistance. Unfortunately it gets misused as well.
