I have finished a downloadable HTML USOpaedia for TFTD, similar to xcomufo's UFO Defense downloadable UFOpaedia. If anyone wants a copy, email me at darth_synge @ yahoo.com.
Upcoming projects include making an HTML or possibly Flash UFOpaedia for X-COM Apocalypse once I actually manage to finish it. The latter will only happen if I can get some Flash software and learn how to use it, though.
I have an account on the xcomufo forums, though I haven't accessed the forum in a long time, and have no posts there. My main forum is Spacebattles.com, and I have the same handle there as I do here.
