No site I have or any I visit, including here link you to vbulletin.com.

Many I have does even vbulletin.com has it (Powered by vBulletin® on the footer) the vbulletin is a link but then again I have seen lots that don't have it

I just want to know because a lot of sites don't have the link. If it's not required it shouldn't be on my footer either. I paid full price for my vb suite so I'm not doing any advertisement for free if not required.

I am not sure if it's a default thing (when I said yes in my other post that was a quick answer I should of looked into more before answering) or owners remove the link. I got the branding option as I did not want all the crap on my footer

I would combine the two lines of navigation so that the login is not in the middle...keep like items together :)

Perhaps move the Announcement to the footer.
