Why are there threads that I can't view?

[Ali Samana]

With this new version there are threads that I can view. I tried to click on a thread that said somehting about 7 foreclosed apartment complexes, and all it did was refresh the forums page. I also tried to click a thread that said something about a DFW meetup, I plan on being in DFW and wanted to attend, but can't see the thread.

If the threads are not viewable by all, then should the show up for everyone? I.E, if those threads are for private groups, shouldn't they only show up to those people that are in the private group?
