Faith, I wish I knew what to tell you. I haven't changed any settings or permissions, and I'm not seeing any network failures being reported, so it's something of a mystery to me. I'll have to contact tech support and see why the comments are no longer working. I don't seem to be having trouble with e-mail, however. Anything sent to my domain, regardless of the name you use,
should reach me. (I just tested this, sending from another address messages to two of my aliases and one made-up jumble of letters. All three messages went through.) I'm not really sure what to tell you.
Thank you, though, for bringing this to my attention. I'd really like to figure out why the comments stopped working.
Addendum: I seem, after changing a few CHMODs, to have fixed the problem. More or less. I can't edit or delete earlier comments, but posting and editing for new ones seems to be back online. As for e-mail, I've received two from you, to which I'll respond. You can also reach me at Gmail, if you'd like. My address there is the same as my domain name.
