I am succesfully update my BlogEngine into version 1.3. It's not preety easy because we need to adjust the settings.xml to be compatible with BlogEngine.NET 1.3 and some theme function is deprecated which should required some modification in my own theme.
Maybe if you send me email, I would applogoize that I would be late to reply since my Portable Mozilla Thunderbird getting stupid and need to backup all my stuff over there. I hope I could fix this soon and trying to fetch my hundreds megabyte email from Gmail. Wacky.
