Thanks gitasan (I notice you haven't bid on any yet!

) The trick is to put the link in your forum signature. At the top of this thread, click the left hand tab (Go), then Personal Zone, then Profile. Over on the right, click View/Edit Complete Profile, then scroll down to the Signature box. Put what you want in there, submit it, and hey ho, Bob's your uncle. You won't forget it again.
EDIT - I just looked at your store, you've got lots of nice stuff

But what you could really do with is some books

I could do a deal on postage!
