You could also not make a infocard if you don't want other to know anything about the character.
But for factions placing rank and role into this is very useful.
Also the rumor idea is a good one.
I have put a small part char backgrounds motivation of why they are in the group and something like 'some say he knows how to fly' although thats a lie ^^ sometimes.
For people who have problems with words sticking on each other do the following:
Example:
/setinfo 1 a He likes beer.
/setinfo 1 a Could be drunk watch out.
Shows as:
He likes beer.Could be drunk watch out.
Example how to split it:
/setinfo 1 a He likes beer
/setinfo 1 a . Could be drunk watch out.
Shows as:
He likes beer. Could be drunk watch out.
