Two questions...
 

I was thinking of buying an additional Vbulletin license but I had a few questions.

I was wondering how long 4.x will be supported for in terms of security updates once Vb5 goes up. I have kind of grown to like Vbulletin 4 and would like to keep using it for a long while.

Will Vbulletin 5 Connect be compatible with ie7 and ie8? I still think a lot of people use those browsers unfortunately and would like to be able to have those people as users too. From what I see there are a few things that I don't like about vb5, but maybe things will change, because I'd like to keep using Vbulletin stuff.

Thanks.
