Looking at Damian's post, I realise he has something that porn can utilise to improve joins, make the site stickier and reward members. Just making it serious and getting away from the webmaster thinking into porn thinking.
Firstly it needs a forum. From the members area people can post in threads or create threads. All to be approved and edited by the administrator.
The threads are users views of the videos, models and the whole site. On some site if the include multi combination, for instance; Solo, Lesbian or Hardcore these to can have a forum So it will need three or more forums within the forum. Like GFY has.
Members are asked to post reviews, comments, observations and ideas for the videos, models or site. In fact anything they wish. The admin will approve or not and edit the post to SEO the post.
Motivation will be in terms of a prize/rewards. The prize is Multi choice and rated on performance. For Instance.
Every approved post gets a point. Number of words are also point related. Also each link from a poster is like an affiliates, if he gets a join off the link, he gets points.
100 points = Free lube, or months free membership, or autographed picture of a porn star.
200 points = Years membership, or scene shot for the member to his needs, or live webcam with a model, or phone call from a model, 1-1 on Skype.
1000 points = Dinner and a night out with a porn star.
Just suggestions on the prizes. The site can decide that for itself.
Kick it off with some posts of your own.
It could be run by an affiliate who is good and capable.
It gives the site SEO forum with lots of posts and shows the site is well attended.
Could even be done with Roald at Freeones with a partnership. Just needs sponsor and forum owner to get together and sort out the mechanics.
It treats adults like adults and gives real interest and interaction between the member and the site.
I can't be bothered so no silly replies on that. I don't need to bother.
It's up to sponsors to take the idea and improve on it.
