I was searching the web for Merlins and stumbled across the Wikipedia entry (see link below).  It is a bit basic, and I'm not in any way qualified to update it, but maybe someone else can?  Between the measurers like GGGGGG for the current rules, the Ancient Geek for some of the more fun stuff from the recent history, and if mags put it together, surely we'd be able to have a really excellent page!

The Wikepedia site does offer redirection to this excellent site does one need more?

Where ?
