This may sound silly but...

[CJWilkes]

Is this the ACP lounge or is it open to everyone?

[Szalam · Accepted solution]

It's open to everyone!

[Jon Fritz]

There are areas that are open only to ACPs or Moderators etc, but the Forum Lounge is open to everyone.

[Peru Bob]

If you are not blocked from a forum, then it is open to you.

I can see where one might think it's an ACP/MVP Lounge but it's not.  Anybody with an Adobe ID & password can post/reply here.
