There _is_ a thread out there... I think it's in the Members Frogs and Vivariums section, it was posted probably six months ago.... I don't remember who posted that they have a lot of frogs, but I remember someone that had at least 300 PDFs in their personal home... forget the name.
It also caused a little controversy because some of us don't think that "how many" says much. A person who has a lot of money can buy as many frogs as they want, but that shouldn't be a goal that we aim for. We should be focused on how well we take care of the frogs we have.... I'll do a search and see if I can find that thread for you....
Edit: Aaaaaand here you go:
Who has the most frogs?
