Ok. There doesn't seem to be alot of webmasters here from the UK; and so here is a bit of digging I did link wise at least for other people looking for uk adult webmaster websites:
http://www.adultwebmasters.co.uk/chat/ - Chat forum for UK adult webmasters.
http://www.hush-hush.co.uk/hush/directory.html - This seems to be a directory for the adult industry in the uk.
http://www.londonfetishfair.co.uk/default.htm - A fetish fair held in London. Might be interesting if you are into the bondage market.
http://www.ukadultsguide.com/resources/Resoruce_Sites/ - Some links for UK adult webmasters
If there are any others people know of; or stuff they wish they had known earlier as a UK adult webmaster then add it here; and lets start spreading some good karma around.
