They probably did.

Right now I'll bet on Alexander Verbraeck's theory of an embedded ^Z over
anything I said before.

I think it's standard SMTP to represent a literal period at the beginning of
a line with two periods so that it won't be taken as the period to end a
message.  However, that happens the same with all articles in your list's
digest issues and wouldn't be particular to Carol's posts.

That can be a locking problem, but it would show up randomly and not select
Carol's submissions.

[I suggested automatically indenting the bodies of her posts by one column
 in case the problem was having some particular string flush left.]

| She didn't like being "moderated," so she left. She was a pretty

| might entice her back, but my posting her messages was my solution
| and she didn't like it at all. Affected her sense of spontaneity and
| autonomy.

If the problem is a ^Z, indenting won't help after all.

Yes, it can be invisible, and there's no telling exactly what it can cause.

Good luck.
