Unless you are a paid Sponsor you may not do anything on the site designed primarily to promote your own business.
You may not link to any commercial non-Sponsor website in your signature. You may not include the name of any non-Sponsor business in your Username, Signature or in your Public Profile including the HomePage found there. This rule applies whether or not you are the owner of the business. You may not have a User Name that promotes your business (Bill's Accurate Guns). You may not post a message that is for the purpose of promoting your business with either text or pictures. Non-Sponsors may post replies of a helpful nature that involve topics related to their trade or type of business in response to requests for such general information from other members. Non-Sponsor forum members engaged in a profit making enterprise who receive a direct request for their services or products in a thread may post "PM Sent" or "email sent" and the conduct their business off line.
