Well, I never use Internet Exploder unless I have to.
I've been moving around the DC site on SourceForge all morning without any troubles at all. I believe that the comment system is for SF users, i.e. you have to be logged in; and it might be that it's for developers only.
If you respond with your comment, I'll put it in for you.
You should be able to view the Wiki, if not make changes to it. I know that you have to be registered for the changes, but don't have to be a developer (I have a little more control over this feature).
