(Before someone looks at the registered date on my account, I played for over a year)
Problem:
There are times when its important to let other role players know that your description should be checked. For example, if your character is in a state that would normally be quite obvious - visually. For example, your character is a child, your character is visibly upset, manic, disheveled, cloaked, reeks like sewage, or is covered in bright green paint.
(For those who are incapable of reading between the lines, the thing about the bright green paint is there only to reinforce my point - its not something that is likely to happen ...*rolls eyes*)
In cases like this, especially when one's appearance/description has suddenly changed,its not uncommon for people to not notice the change. Checking people's description every time you run into them gets tiring - especially when the other person has a page and a half description and you are rushing to keep up with the conversation at the same time.
Solution
Allow the player to add a tiny string just above their name tag. This way they can add a tiny note to alert other players to their changed appearance.
For example, a player might add a simple word like "smiling, frowning, child, injured, cloaked, painted(again, refer to note above), wet, floured, unconscious, please_read, or whatever to quickly convey some useful info about the state of their character.
I do realize that this could be abused... Surely some nitwit will set it to something like "--=( I'm dope,yo? )=--", "justin beeber" or n00bl3t sp3ak but the ability to use this could also be revoked, so I don't see it being a huge issue. On the contrary, if I see people put dumb stuff there, it will serve to let me know that I need not bother trying to rp with them as no serious role player would do something like that.
If allowing a word or tiny phrase is too much, then how about just allowing the player to flip on a flag - putting a "!" above their head - or a shebang "#!" If the bang is too wowish o_O.
I think this is.a fairly simple and generic solution. For those who hate it, perhaps it could be hidden in options?
