Beltchecker or BJJ Globetrotters? These are two different things? :)

Here is a map of where Beltchecker users are. but I'm fairly sure that's not what you mean: https://www.beltchecker.c[...]p?p=global

Yeah, I stopped updating mine years ago, far too much work (I did it all manually, checking each club before I added it). Especially as once I put a club on there, often they'd change location in the future: I wouldn't know unless somebody told me.

There have been other club map sites in the past where people just entered their location themselves on a form. Much less work for the person running the site (once the initial coding is done), but then there's no quality control.
