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
