Thanks Trevor - I've just tried, and get the message - user name taken. Well, yes - that's me. It's because I changed my email address when I changed supplier. Too difficult to bother trying to explain.
And whilst we're on the subject - why do we have to sign in so often? I find that almost every time I visit another site, when I come back to the forum I have to sign in again. No wonder there's less input on the site.
That frustated me as well AJT, now I just open another window to visit another site, then come back to this site on the original window ! (Hope that makes sense)
