I check out 3D Chat all the time to see if anybody escaped from the FPSC forums and is causing any havoc...
Seriously,I check it fairly often since I have moved several threads over there.
You can post your models there and if someone wants to they will make them FPSC ready like Loc said.
The best thing you can do is search the forums and find the tools (all free or at a very low cost) and there are several threads on importing models and making them FPSC ready.
If you are serious about making games at all in FPSC importing models into FPSC is most certainly basic knowledge you will want to have.
Also I would check out Nickydude's beginners guide.Just click on his sig in any of his posts and check it out.It has a lot of useful information.
