Well..
I have cuzyoosuk.com pointing at the main site, i had cystoons.com pointing at the toon site, and inspiredesigns.ws pointing at another part.
So really, I only have 1 domain to a section of the site, and inspire's a completely different site. So.. I'll go with 1.
I also own learngfx.com, but im not using it. ¬¬
