> I fully get all the excuses [..]
No Frolin, there *have* been significant e-mail delivery issues. For instance, for a long time, AOL/Compuserve used to block e-mail from the IP-range that cerious.com is part of (not cerious' fault). Also, many users and mail providers do have pretty bad spam settings.
While I agree that Cerious' responsiveness seems sub par and unreliable (something that I'd hoped this forum would help resolve, but Cerious' participation here is minimal too), the few cases that I've seen looked into all turned out to be related to e-mail delivery problems.

I can't remember something if you haven't mentioned it before.
In closing, if your messages concerned beta versions, I don't think you should be expecting any responses to begin with. As buggy as the regular releases may have been, the purpose of beta versions is testing, not production work, and bugs are expected.
