Hello! Glad to see this is still going strong. I have several ideas so I'll sum them all up here. Ideally that'll give me some latitude as far as party roles go.
I've been playing online games for about eight years now, wayyyy back when me and my group would try to use ICQ and the honor system for dice rolls.

We've come a long way since then, of course. I love games that have high adventure and plenty of action, but I'm also a very character-driven player. Hence, RP is very important to my enjoyment. Of course, I see things like combat and action sequences as just another form of RP, so I'm not as hard to please as it might sound. I love interaction and dialogue with other characters though, and I find the games I like best have a sort of rhythm between intense action scenes, and quieter 'downtime' moments where the characters can talk.
Concept 1: Aliyas One-Arrow
Human or Elf Fighter 2/Druid 3/Beastmaster 9, Ranger 12
Uses core SRD and Complete Adventurer for Beastmaster PrC and some feats.
Aliyas would be a mounted archer and "medium cavalry" unit, depending on terrain. Space permitting, she'd use her mount to keep some distance and rain arrows on opponents. In tighter surroundings, she'll charge in with her longspear and dire wolf to do some damage in close. Minor spellcasting used mainly for buffing self and mount.
Concept 2: Proteus
Human Druid 5/Master of Many Forms 7, Fighter 4/Rogue 8
Master of Many Forms is in Complete Adventurer.
A loyal agent of Silverymoon, an incredibly gifted spy, and an inveterate prankster, Proteus has embraced druidism as a path tp grasping his own inner nature...and in so doing has unlocked an unlimited fluidity of self. His sunny disposition and love of entertaining belies the fact that he is a canny and underhanded schemer, and that many of his shapes are deadly in the extreme. Proteus sees himself as an artist, with his own flesh the palette and paints, and is always seeking out rumors of strange new creatures, so that he can learn their shapes and add them to his reporatoire. Though he has worked for Silverymoon many times in the past, he maintains his official independence, though in truth he loves the city and what it stands for, and would defend it to the death if necessary.
There's more, but these two are the most thought out so far. Thoughts?
