No special section for showing WIPs. If you're building aircraft, post the pic/pics in the Aircraft section. If you're working on ships, post the WIP in the Ships section etc.
If you put your question in the General section you might get a lot more replies. The question of showing your work area has been asked quite a few times on there. Try searching the Forums and ask for "Pics of Work Areas".
Good luck.

Main WIP:
On the Bench: Artesania Latina (aka) Artists in the Latrine 1/75 Bluenose II
I keep hitting "escape", but I'm still here.
