Welcome Michele!
What parts of trinity are you interested in working on? We have a bug tracker which can provide a useful starting point for new developers.
Thanks for welcoming me. First of all I am looking at getting everything to compile on my laptop (seems to have some problems right now, but I am working on that). After I reach that point (and after my coming Xmas holiday break :) ) I am planning to try to add a couple of features to Konqueror (small things but I find them quite useful on another shell). After that I will take on some bugs from the bug tracker. My main expertise is C/C++ programming, even though in a completely different environment and platform. But I am confident I can work my way through with TDE. The only limit is the time I can dedicate to it, but I'll try my best. Hope to be helpful soon.
Cheers Michele
