There is a lot of spam in the replies here, the reply from Ian Pack is a blatant one as a quick search shows he works for the company that he is "recommending", I would not be surprised if more are spamming.
Another one in the thread, David Foster, is the Training Manager of the company he is touting.
I don't want to link to these spammers' websites.
I did a search of the name, product and company and both cases are employees spamming their products.
