Which one? Of your 3 geeklists, it looks like 2 already have a life of their own (the PHX area ones) and the other (garage sale tips) is mostly static.
That is, why can't others just post as themselves? Perhaps with your blessing/designation in the header. Why does ownership of the list itself need to change?
I am talking about the virtual Phoenix flea market and the Want to buy list but that one is pretty mild by comparison.
I don't do a ton of work on either but I don't want it to get neglected - sometimes issues arise that need resolving, questions answers, 'is this okay to post?", kind of thing.
The listings are added/removed by the sellers and buyers/sellers reach agreement among themselves. I just thought if there was an easy way, to pick someone who wanted to take over we could do that, but if not (and I can't see an easy way from the site), I'll just ask someone to sort of be an assistant geeklist owner have them monitor it and text/email me if/when there is something more drastic that needs addressing.
