Why on earth would I delete you? And I wish more people would get that. I think forums are a great way to help others while still promoting your business. You gain respect through your useful information you post and people are more likely to visit your site.
So many spammers think coming on a forum and posting one advertisement is the way to get traffic. Not only will it get your post deleted but most people know spam when they see it and are certainly not going to visit the spammers site.
Being real with people is one of the best ways to build credibility and that's the approach I've taken online and it's worked. You are never going to please all the people all the time (as the saying goes) but if you value your integrity, be honest and stay true to yourself, it's hard to go wrong.
Welcome, by the way.
