I'm not sure it's a big deal or not. I think Historic may be wondering what an advertisement for a business is doing in a chat forum that has been professed to be against such an act. But I could be wrong. It may be ligit and SN is being compensated for the add space. Probably so.
If you are referring to Allcarfan's signature line I think 302 is right. I think he does powder coating and that is his way of letting people know. I believe as lomg as someone does not start a thread promoting a business it is fine to have it in your signature. But then, I guess since you started this thread he will be enjoying some free advertising.
see what happends when you disagree with someone on one or two posts? You get them to start to try and stir stuff up. They just cant seem to let things go.
Powdercoating is a little something I do on the side....and I do it quite well.
