Welcome to the PB forum. As you have noted it is an outstanding learning tool and we are glad to have new folks join us. There are a lot of very knowledgeable people on this forum and as DD (Dave Davidson) has noted it is next to impossible for the collective group to be caught unaware. That is evident from this thread.

The selling of products here is discouraged (obvious sales attempts are not allowed) and certainly any post that could be viewed as such should come with full disclosure of all facts and representations. Bob may want to address this directly. A product that works is its best advertisement so if anyone has a good result with a product just post the pics, facts , proof etc.( Not the product name , company, etc )and tell folks if they want to hear more then contact you by email. I am not sure that process is ok and is up to Bob. Most of the people here try to support the PB advertisers so if you have a good product then that is a good source.
