When people look while in a room, they normally see someones name and their title. What I want to do is set it up to where if someone looks in a room, they see someones long description, and if someone doesn't have one, then it will show their name and title just like normal. I also want it to show someone short description, if they have one, when they say something instead of their name, and if they don't have a short description, i want it to show their name like normal. I have looked at about a million different places to see if I could figure this out, but I can't seem to. I guess it could just be as simple as making a skill or command within the mud, but I don't have the faintest clue.

If you're using ROM, open up act_info.c and look around for this function:

void show_char_to_char_0 (CHAR_DATA * victim, CHAR_DATA * ch)

That's where you edit what you're after. If you really can't figure it out after examining the function (I did so it can't be TOO hard hehe) then post again and I'm sure someone will lend a hand.
