Thank you for the feedback.
As I did a import from myBB platform to Vbulletin, so few things may have messed. I will fix the Avatar problem soon.
Regarding the same header on blog and forum, I need to work on that. I already have that in my to do list. But no time frame on that as it requires a bit of playing with the code in which I am weak.
Update : - Check Avatars. It should work now.
