I can't find any detail on the license conditions, to answer questions like:
• is the 'license' for a single server, or for a single domain?
• if it's for a single domain, can it be used on multiple sub-domains (in case there is more than one forum community within the same domain, eg. developers and marketing people)
• what are the terms of support, does it include entitlement to minor upgrades like x.1 or major upgrades like 1.x?
