Forum type application/starter kit for Internal Site

Jan 8, 2010 at 2:25 AM

Hi All,

 

I am trying to create a forum type application/site for internal use within a company. Basically, I want to create a forum where people can post questions and subscribed people will get emails.

 

Is there an application that can be created easily (some open source application?) or bought for a reasonable price from somewhere?

 

Any direction would help.

 

Thanks you
