Well, yes kind of. It's a gray area. If you post it for him, then the thread would be yours and not his. This would make you reasonable for the thread. As you well know, if an issue pops up either df2x4 or myself will address it. It's a little like you selling something for a neighbor on here. It has to go through you. These rules are set up the way they are, to make it more difficult for spammers, and for the sight to not turn into a sight with mostly junk for sale. It's more of a curiosity for active members.I don't think it was directed at you as an individual.
@df2x4 or @kennythewelder what if one of us who does have the ability to start a for sale thread does so for him? Is that a violation?
