Several list members have seen their Math-Fun postings held for moderator approval. I've approved all of these, so they are eventually posted, but typically with a half-day delay. The rule is that list members get to post without approvals or delays. Unfortunately, the predicate for "is a list member" seems dumb: it looks like the "From" address on the message must exactly match the subscription address. So if you are subscribed as joe@fermat.math.univ.edu, but you post your message from joe@gauss.math.univ.edu, the message is treated as a non-member posting and dumped in a box for me to approve. Each time this happens, I add the new address to a white-list of "extra posting addresses that are ok". Eventually we'll have most of the alternate addresses, and this should become only a minor nuisance. If you want to change your subscription address, the only way I know of is to unsubscribe and resubscribe. You might want to resubscribe first, since I also have to approve new members, and then desubscribe later. If the web interface is too unfriendly, drop me a note and I'll handle it. On the bright side, I've discarded an average of .5 - 1 spam/day that was headed for the mailing list. These are forwarded from the old math-fun address; I've left that open while folks adjust to the new address. Rich rcs@cs.arizona.edu
