IA in chat
While not strictly banned, the twitter format for the rp doesn't really work for IA. The intended effect is people tweeting each other. So IA posts don't really fit, unless there is simply no way to imply actions in text.
For example, *gives BB a hug* would be an example of an unnecessary IA post, as would *enters the cave*. "@yjbeastboy give me a hug" or "why is the cave such a mess?" are more realistic-sounding tweets that accomplish the same thing.
If tempted to IA, ask yourself: is this vital information? If the answer is yes, ask yourself: is there any way to imply it in text?
Secret identities
Remember thatg some characters have secret identities even from other heroes (like the Batfamily). Remember not to "out" them. Calling them by name in DM (assuming your character knows their name) is fine.
Joining
Don't just start posting, it confuses everyone. To join the rp, contact a member of the rp in advance. The best bet is contacting Mera, Aquaman, Secret or Miss Martian, as they've been around the longest. Note that there's been a recent influx of new members and there may be delays in accepting new characters until the rp stabilises, depending on the situation. New players may be invited for a chat interview or have a short trial run before being accepted, to ensure consistency in rp culture.
Staying In Character
A couple of inevitable differences will arise between the rp and the show. Members of the Team in the rp have a cookie addiction not in the show, and some of the interpersonal relationships change a little. But people should try to stay as in character as possible and adopt the same personalities and general attitudes as their canon counterparts.
Characters
Only characters that exist in the 2011-12 Young Justice canon are viable.
RPing with non-members
RPing with non-members is allowed.
