I developed a members registration system for my game site: removed using PHP.
A member can save its favorite games, and return to play with them whenever he like.
To use this feature and register for the first time, click the Your Favorite Games link, found on the header of the website.
In order to add game, click the Add To Favorite link, found below the game you want to add.

I will be happy to hear your feedback about it, as this is the first time I developed a registration system

review board

If you want someone to take a look at your code you'll need to post it (which might be a good idea for a registration/login script). If you want people to give you feedback on the design of your site use your existing thread on the review board.

Thanks, I want feedback about the functionality of my registration system.

The language you use to implement that functionality is completely transparent to a user. You can use the PHP forum if you find a problem with your registration code, but regarding the functionality of your site, please use your existing thread in the website reviews forum.
