This is more of a curiosity question than anything. I notice that at least on this particular site, in order to access certain parts of it, the forums, for instance, one has to know the actual URL. Also the login page seems hidden as well. Was that an administrative decision of DNN corp? Or is that the way DNN sites are supposed to look, or what? On my site, everything is out in the open, and there are no "secret" urls. What is the rationale behind how this site is created, so that I know what to emulate and what not to on my own community sites? thanks.     

It a     ctually turns out that issues I thought were with this site are actually related to accessibility and the way screen readers see the page. Some links are not visible to screen readers at all, or not with the way the site is skinned, anyway.

it's got to be some third-party extension. One of the members of the community act          ually mentioned that in a Twitter conversation we were having. I know this because in a default installation with all default extensions, the links that are invisible to screen readers on this site are visible there.
