When I reach your forum via google, I get redirected to myfilestore dot com. I do get to the forum if I go back to google and do it again. This is NOT a client side issue but is a known issue with your forum software. This has been happening for months and just returned to the forum and see it's still not fixed.
It makes me worried that this exploit has been out there for months and has not been noticed (or resolved). Hopefully the security of the product itself is handled better.
