Landing page?

[all-in]

I have vb already up and running but need to make a few changes. I want to keep one board but have different landing pages/domain names pointing there. For example: if my main board is www.mainboard.com/forum, can I have a landing page for www.landingpage1.com, www.landingpage2.com, www.landingpage3.com etc and have a tab of each of those that directs to www.mainboard.com/forum?

Hope that made sense..lol
