Thank you all for the votes of confidence, I have been in contact with Dave and he is happy to make me moderator, or to leave the forum without a moderator.
My thoughts are more to do with whether or not the forum needs a moderator, as I understand it the main powers a moderator has are to remove any unwanted posts such as spam, and to split a thread if someone posts a separate ID request on the same thread as a previous poster. That doesn't happen often, and if there is spam then I feel that Dave would prefer to know about it so he can deal with it appropriately.
Thus, the need for a moderator is, I feel, not sufficient to create the position. I think green has put it well, you all know you can call on me whenever you think I might be able to help, if someone isn't aware I can be called on there will always be someone else who is aware who can give me a call up.
I humbly bow out at this point in time, but expect to see me around.
