The rule is:
"New members are not enabled to post New Topics in the For Sale forums until they have demonstrated knowledge of the forum and how our online community works with their posts. After 8 such posts, including posting an image, new members may request an upgrade to regular privileges."
Posting a normally sized photo is required. The rule does not say "8 pics."
New members may sell on eBay and post an announcement about it on our "Online Auctions, eBay" section of the forum.
If you are still confused, you can read over the "Welcome... READ FIRST" email that we sent when you joined the forum, or send a message via the "Contact" link at the top of this page.
