I suddenly stopped getting e-bots yesterday, too.  I checked in the gallery this morning, scanning for comments relating to the subject, and I see a few other people are having the same problem.  I'm getting other e-mail okay - just not from Renderosity.  

This is NOT about receiving the newsletter - it's just about e-bots!

No notices that people have commented on my work (although I got several comments overnight) and no notices that my favorite artists have posted work (and I see many of them have).   

Any information available on this problem?
