SMF 2.1 is awesome. It really is an amazing update from old faithful 2.0.15. In my particular case, I had to deal with several major problems but, little by little, and with the awesome support of all the SMF family, I am a super happy upgraded user. I loved SMF 2.1 RC1, but I will surely love RC2 even more. Thank you so much for supporting my community since 2008!
