Hi. We don't have a list of wikis that are currently up for adoption. Some wikis, depending on when they were created, will have a small blue bubble that appears for users saying the wiki is eligible for adoption if that wiki's admins are no longer active. Those who want to adopt it can then do that, so it's really a case of finding a wiki that's eligible for adoption rather than searching through a list of them.

If you don't want your wiki to be put up for adoption, then you'll want to make sure that you edit at least once every 60 days. Otherwise, that blue bubble will appear, or (if that feature isn't on your wiki) someone can request on the requests page.

I also just want to clarify that "Founder" isn't a rights group, just an indication that you were the person who created the wiki. In terms of user rights, a wiki's founder is no different than any other user who has both admin and bureaucrat rights on a wiki.

I hope that this, combined with TyA's response, answers your question!
