I have one domain "www.example.com" and am currently running a forum on this domain on a host.  This host is also storing some media files, eg: videos.  I have recently obtained a reseller, and would like to have it under this domain as well "www.example.com".  If I make accounts on this reseller, I would like to have the subdomains like so: "www.sub1.example.com", therefore I would need this reseller to be under my domain.  Could I have my forums and reseller on the same domain?
