WordPress MU

Hi!

I need help. So i want to create a public site where people are posting avertisements on what they are selling or if they want to exhcange something or sell something. Just like the idea this site here has - http://www.ss.lv

I have looked all over the web, searched forum, but i dont even know for what kind of terms really to look for.

Maybe somebody knows this, i would be really glad if you could share!

Classifieds is the word. :)

http://wpclassipress.com/ is a paid theme that does it.

Here's the plugins:

Thanks so much!
But is there one that you could suggest that would be easy to implement, manage and also free :) ?

The second link is all free plugins. I haven't used any of them.

Andrea, I am using classipress for my wpmu, but its been nothing but problems with thumbnails -- I got no support on their forum, but I must say I got some help from David (the owner) -- but I still cant show thumbs for my listings -- though I must admit I have had the problem with wp classifieds and next gen image gallery -- if you know a fix I would really appreciate it

Does it use the timthumb script to generate thumbnails?

not sure, how would I find out? this is the site http://www.homehost.com
I did try different themes and I couldnt get the images to upload thumbnails?

the theme I am using now it classipress --
