You may post in the various city and National Forums as frequently as you would like. You may post a (read One) Welcome post/ad in the Welcome and Introductions Forum per the following:
The "Welcome and Introductions" forum in each Metro Location is an excellent 'landing pad' for new ladies to the community. These sections have excellent readership from the members in that particular city. New ladies are welcome to make a post in this forum during their first 7 days of membership. This will be called their 'intro ad' and may include all their details, info, and pics. This may be done before you have requested VP status or while you are waiting for approval. Once approved, however, please use the appropriate forums to advertise and post in this forum only to welcome new members.
Once you get Verified Provider Status (if you desire it) you may then post regular ads. The guidelines for all of the posting areas are found here:
