Please make it possible to sort a forum by posting date

If people are going to  use the web interface, they need to be able to quickly find new content or material they are looking for.  

Right now it appears as though the only sort is based on the last comment.  But if there are threads that a user is not interested in, you have to sift through those again and again lookinf for new threads.

Please make it easier to filter and sort a forum so that information is easier for people to browse.
