I too have a website where I need to allow anonymous users to post to the forum.  Some people just want to post a questions without having to give out an email, username, password etc.  With all the spam, I can't say I blame them.  Another highly used website forum that allows anon posting is www.sqlteam.com.  Keep up all the good work. 

Can we set up some kind of poll to see how many users would find the anon posting useful?

First I appreciate all of the hard work on the module. 

This is another use case for you to consider.  The Government Agency that I work for wants to allow users to post without having a username or to register so, if their question could lead to reprisal or other problems, then they can't be indentified.  We already have a forum system running under PHP but there is a new idea that I would like to use the DNN Forum with for simplicity.  It is a requirement to have Anonymous postings.  The PHP forum already implements this and it would be required to switch from PHP to a DNN module.  As an addition, I can think of at least 3 agencies that use DNN that are related to the one I work for and it they were to implement a Forum the same requirements would have to be met.  The Forums, of course, would be Moderated and the url would only be available through Email contact so it would prevent massive spamming or other problems. 

As a side note,  after reading the earlier postings to this forum it highlights one of the problems that I have encountered more and more with DNN.  I think some of the members of the projects and core teams have forgotten something.  We, the users, are the consumers of your product.  I do see that Anon. Posting may become a feature in the future which may be a good or bad thing depending on your point of view, but the way the inital suggestion was handled in the early part of the forum highlights the problem.  If you treat your consumers badly they will go elsewhere, then you will no longer have to worry about the product because it will cease to exist.  I just think some of the earlier replies could have been handled in a much more appropriate manner and they have taken away some of the unhappiness.  If I had just read the first couple of pages of this posting then I would have been very turned off where it was handled much better in later pages.  Just a thought or two from someone who is starting to see apathy and rudeness in many of the replies from some of the team members for Dot Net Nuke.
