how do you post an ad on this board?

regional board and touch base with the Moderator. I think you're allowed one ad per week.

do providers actually post on TER. If so, where does a hobiest go to see the posts. Thanks

their ads on regional/local boards.

ads.  Just go to the drop down menu on your left and pick those boards for your viewing and hobbying pleasure.

You don't actually have to touch base with the moderator.  If the ad is compliant, then it will be posted.  You are allowed one every seven days.

Thank you. I have found what I needed.
