It's a difficult thing when we get to whether recommending a company on CBF is advertising or not and I wish it could be clarified easily. For things like transfers and tradesmen I am always keen to see genuine recommendations, with contact details. Not just because it is the best way for people to find good, honest folk, but also because posts that say "email me for details" are often, sadly, the way that people earn a cut from sending customers to the company/tradesman.
CBF is a public forum and all this "I have details of a great plumber/transfer driver/builder, email me for details" has no place here. If it's good, tell us!
