I don't think the warning was directed at you specifically it is aimed at reminding members that Guest posts may not be what they seem, but they still want ot keep the facility for exactly the reason you point out, but the facility has always been to just ask ONE question, and then to join.
Members of the forum have all levels of expereince from none to a lot of years and it is about shring expereinces and problems. We want people to join so that we know who is posting (not that we really know as it is after all still private as we use nicknames). Just join.
:D :D :D :D
