When/if you create your trepia account on a wintendo, please set your icon and fill in your profile there. It should save it server side, or at least that is what I have found in my limited testing.
There is also an issue with it giving an error every once in a while. We are aware of this. It happens in gaim as well. It disconnects you if you use trepia via gaim, and also with adium. Adium luckily reconnects when it disconnects.
