The one email on the bay12 site dont seem to exist anymore, other places i click on an email link, only to be met with my inbuild windows email app wanting me to make an account, which i for some reason cant.
Just recently (last month) I had to send an email to Tarn, and I had immediate joy with the obvious contact details plucked straight from the website. I can't imagine that changed since, so maybe have another look?
Your other problem is maybe something for The Generic Computer Advice Thread, over in General, but sounds like your browser's default behaviour on clicking an email URI is to open some 'default' email software (or maybe redirect to a web-based portal) that you haven't set up, when you actually use another one (which you or the place you got your machine configured set up with such arcanery as the POP3 servers and required passwords).
That probably needs more looking into and some settings changing (configure things according to your use, not how the machine thinks you use them), and you must have valid email
somehow in order to have registered to the forum, but that is for the Computer Advice thread to mull over, not here. Or if you have difficulty copy-pasting the Contacts address across, in solving your first issue.
(Tarn/Toady was certainly happy to quickly reply to me, on an issue that was mostly my problem. From what I already know about the question you ask, it's likely you won't exactly get a 'solution' but if the reply isn't friendly I would be very surprised.)
