What are the guidelines regarding ads and promotions?
Please put the tag [AD] (with square brackets) at the beginning of the subject line. When posting to promote an event, group or product, please include only a short description and its web site address (and/or email address) so that interested parties can contact you directly. Repeated ads, especially in a short period of time, are frowned upon. Please make sure you have read everything in this document to avoid potential conflicts.
