Where to find projects on the new site i.e (http://k2underground.com/k2/ProjectHome.aspx?ProjectID=3)?

i sent an email to Underground@k2.com   and no body replied to it

What is the name of the project  you are  you are looking for?  You can go into blackmarket and see all of the projects.

thanks for you answer...i checked the k2blackmarket but it seems to only host one project... where can i find the old ones

I'm not sure why you are only seeing one project as thats not what I'm seeing.  However, I looked at a previous post which gave a description of the old ProjectID=3 and it appears like you're looking for a way to modify or work with the Active Directory.  Here is a newer project which looks like it'll meet that requirement:

Thanks for the reply ...but how did you find it?
