As a team we were pondering on the number of test Zingzam communities we have created as part of our development and testing since January...
Well I've cleared out the test communities on my desktop machine 3 times - each when I got to around 300 communities. So that's at least 900 for me.. we reckon team wide (and in staging environments) it's around about the 4000 mark since January 2010. Wow!
A whole heap of test sites..
