At least you’re honestOn the topic of it being custom coded - well done. You’re one of two people on this website - me being the other one who has the balls, if you can call it that, to do something unique and different. Power to you, wish you every success.
On the topic of the community being invite only - I hate it. I suppose this is because I have always loathed the idea of a community being invite only unless there’s a *legitimate purpose* for it to be invite only - and with yours, there isn’t. All your content is public. I don’t see why you’d make your site invite only when there are many ways around the spam issue that don’t necessarily result in you pigeonholing potential members.
