OK ...it's my first idea so please be gentle with me....
I was thinking, if the friend names on the left hand side of chat box could change colour when someone reaches a new level it might be a kinda cool idea. That way friends could post IM to say WTG or if really close send a little somethin' somethin' to them.
Of course if this is not practical for the Dev's fair nuff and I will crawl back to my space and never bother you again...but ...I thinks it a good idea and would love the + support too :D
