UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Licence question

Hi
I have a UBB Classic licence for a site that's no longer in use.

I want to use it on another site - (it's an old licence and I don't want to spend any more upgrading, unless the site takes off).

Do I need to *do* anything to fulfill licence terms and agreements?

Cheers,
H.
