I've been looking for an emule site like Dead Donkey that specializes in cult & exploitation films. DD does have a fair amount listed, and those type of films do seem to be welcomed here, but I respect that this site is more about the Horror & Sci-Fi genres.

If a site does not exist, can anyone give me advice on starting my own? I'm most interested about host providers that won't mind a forum full of ed2k links.

For exploitation, take a day off of work/school (whatever you're into) and try to open the UEC, the Ultimate Exploitation Collection.

It's on these boards, under Collections in Progress.

It will take you some time until it's loaded, though (that's why you have to take the day off )

Cult and the likes are not only here, but I suspect they are at SBiG as well. As I still haven't registered there I can't give you all the details. Maybe someone from SBiG can fill you in.

Sweeeet! That section will keep me busy. So if I start a collection, let's say on Doris Wishman, will that increase the likelihood of missing movies being posted?

Yup, but you will have to draw attention to it (for example, by posting it in "Collections in Progress", so others can see what you have).

Actually, anything other than staying home and waiting will increase the chance of other movies being posted

Yeah, I would try SBiG, too. They definitely love the exploitation.
