I've seen users who have signatures selling products/services. They don't have a thread in 'For Sale', or 'Services Offered'. Their signature just says "I can offer you blah blah, PM me". Is this allowed? Is this within the BHW rules framework? Also, on a similar vein, I've seen threads in the BH Tools section asking about some tools, and others replying that they can sell it to them, and to contact them through the PM. Is this allowed? Can one of the mods, or a member who know the rules, please clarify? Thank you.
