I did some searching and found very little on the topic! I did read in a developer chat that Ironclad wished to have put more character portraits into the game. That's fine. I am glad that they are aware of that.

What I would like, however, is the option to put my own portraits in there, and my own faction symbols. If the fear is that people would create profanities and inappropriate symbols, I'm not sure if that's an actual problem. Games such as Dawn of War does this and I found it to work just perfectly. Other games, in other genres, such as Lineage 2 and Pirates of the Burning Sea (user-moderated), also does with the community-created items. The good thing with Sins, being a non-MMO, is that you ultimately can choose who to play with - thus the community would probably moderate itself to an extent.
Am I too far out with this request? It would really be nice, from a role-playing and immersion perspective, to have this option even in multi player (I know that files can be edited for single player).
Edit: Now that I made this thread, I realized that there were several forum sections I hadn't seen before, so I might have missed a thread about this. Sorry about that.
