The idea is good but I don't see how it can be done. Terry wrote the software for the main site and has programmed the main site badges so they are automatically awarded. The forum software is 'off the shelf' with a few tweaks by Terry, it doesn't link well with the main site, hence the two different logins.
The badges would need to be awarded manually which would mean someone counting up the photos. Only the administrators have access to the various control panels.
Another problem I could see is that some of the members are 'badge crazy' and it is possible that we could be flooded with people posting what might be copyright photos just to get a badge.
Although the idea is good, I cannot see it as viable.
