The attached link provides a comprehensive list of hows and wheres of posting an ad.

My interpretation of those rules goes something like this...

If more than one ad shows up in your 7 day history, the new one won't see the light of day.  I TRY to allow the 2nd one if the original will fall out of that history in a couple hours, but I can't promise that I'll notice.

Multiple postings within 7 days will almost always get you moderated.

If you post something with a picture and a link, I consider that an ad.

If anyone has questions, please post them here, since others will likely benefit from your thoughts.

Thanks
