Hello from Richmond, VA
I can't access the forums on my Android smartphone either.
My thought is that there's something wrong with their mobile version of the forums section of the site. However, I tried using the "Desktop" version too on my phone...and no go. I can access all of Sherdog on my phone EXCEPT for the forums.
Don't worry though man...I'm sure they'll fix it as soon as they can. Page views = People seeing your ad sponsors = $$...so they're losing money right now for sure.
Hope they're on it.
