Indeed, I don't see anyone mentioning Seppuku Arts or Ozark Games...wait I just did. (I did make a post about mine for web design comments and questions - those posts are fine as the purpose is for people to look at it and answer questions rather than to sign up)
It's nice you're doing a website with a community, a lot of people do that, just chuck a link in your sig - advertise through product announcements or tutorial announcements. If people want to visit, they'll visit, people visit for my tutorials, I had a few comments from friends, but the community part never happened and that goes with most user websites - because more often or not what you've got on offer there tends to be here or what people here don't need. I mean Ozark Games has about 4/5 active members - and Keith sells model packs, gives them away for free, he used to have compos for the FPSC community directed - my original set of tutorial, a whole range of sections we don't have here on the forums. (Keith, I'll have the £5 wired straight to my account for that bit of advertisement you're paying for, cheers.
