Not at all, it's just good marketing. You never know when a buyer could be reading a thread. Keep the faith and all that.
Does anyone want to buy this? This is a very strong domain for anyone that wants to set up a UK forum that covers a broad variety of topics. The name is authoritative and that in turn may attract forum contributors as they want to be seen as "expert".
I'm personally a much bigger fan of plural exact match forum terms , for example expertforums.co.uk is available FTR , if you thought it was that good of a name im sure you would have protected the brand and brought what was available.
