Newsletters and Required Registration

[fancominc]

Hi all,

I'm thinking of sending newsletters to users biweekly to remind them about my forum if they have forgotten it. But is there any mod that can do this? I'd like to send the newsletters via email.

Also, my forum is a fashion forum (www.vietmot.net/forum/home.php) so there are a lot of pix. If I want to require users to register to see all the pictures in a thread (they can see the first few), what mod I can use to achieve this?

Thanks so much!
