(belated) Happy Birthday! For the record, I actually tried to post this on your birthday, but I had a problem with the the captcha when I tried to register
Yesterday, i was refreshing/removing some of the addons installed on my forum and yours were the only ones, which i could not even think of removing... Keeping them FREE is an icing on the cake... Thank you, Salute!
