Dear Forum members,

Recently we had two messages 'unsubscribe gap-forum' sent to the
forum, at least in the first case just because of a change of e-mail
address. May I remind all forum members, who want to unsubscribe for
whatever reason, that they should *not* send the message

unsubscribe gap-forum

as well as (in case you want to subscribe under a different e-mail
address) a message

subscribe gap-forum <your full name>

to the forum since it then goes to all forum members but has not
automatically the wanted effect.

These messages *should* be sent to the address

miles@math.rwth-aachen.de

The requests will then be fulfilled automatically.

Thank you, Joachim Neubueser
