Sure, why not...
It really is unfair that people only put Amiga related items in the Amiga marketplace. Hopefully more people will follow your lead and we can make this more of an open setting.
It would make finding the on-topic sales a bit tougher, but it's probably worth it.
Besides, some hobbies, (and Art is a good example) don't have a very big online presence, and is tough to find a targetted market. I'm sure some Amiga fans are big into buying artworks.
I have some things left over from my yard sale last weekend that I'll post shortly.
(Mostly old clothes, but I'm sure someone will find it beneficial)...
