The policy seems to be that for sale ads are allowed for contributing members. If your first post is a for-sale, it will most likely be deleted. They are really trying to have a discussion board, not a market place here.
If you were following these forums, I suggest you hang around for some time - this board is a really cool place.
From human point of view, if the moderator who deleted your original sees your thread again in a few minutes, he'll be annoyed and delete it again. Wait a day or two, post some, participate and then you should be ok.
OK..Here's the deal. This is not ebay. We let contributing members let other members know if they are selling an EB/MM guitar/Bass. This forum is for the discussion of EB/MM instruments and things related, not for the sale of said instruments.
You are more than welcome to hang out and become a contributing member, and I hope you stick around, but like I said, we don't want the forum to become ebay jr.
