Right, prepend removes the first occurence, that makes sense. Just
hard-coding works fine in this case, since the dynamic tag isn't
really needed. Is there somewhere in the documentation that talks
about the #[]# syntax? Since #value# is how you do it without the
iterate tag, I would assume people who try to use this in the future
will make the mistake of doing #value[]# instead of #[]#. We might be
able to save them some time if put an example of using the #[]# in the
documentation.
A totally unrelated question, did something change with the mailing
list server or is this just a weird gmail thing? The reply-to on
every message I get is set to the person who sent it, not the list.
So when I hit reply, it puts the person who sent the message in there.
