Thanks for pointing out that the CAVS Beta corner wasn’t restricted to users-only; that has been fixed.
The reason that these are restricted (and thus impacting your RSS feeds) is to be able to maintain some measure of control over who downloads the Beta. Comodo is very relaxed about beta-testing, but do want to make sure that every “joe” that drives by doesn’t pull a copy and then scream because his computer got hosed (to put it in very loose terms). Registration is free and simple, and is the only caveat to beta-usage.
As far as some of the aspects of the forum, not all of it is within Comodo’s control (it’s not their software), any more than the CFP GUI is within user control…
You should be able to get the Announcements forum to feed thru; there should be a post there when the Betas come out.
