One forum two domains?

[CDRlab]

Dear All,

I want to run VBB for two websites. It will be running on one server, but two domains will redirect to it. Now the most important questions:

1) I want to use completelly diferent style for each. But both sites will share the same forum contents (forums, threads, etc). How I can distinguish the traffic directed from each site? Maybe some ready to use script?

2) Will I need two licences to run this?

Thanks in advanse,
S.
