Hi Sabine.

You should only have one Mudcat membership and stick with that even if you are using more than one computer which you can update at any time. Duplicate memberships cause a lot of confusion and are one of the few things people are asked to try and avoid doing here.

If you have registered at Mudcat, all you need to do is go to Membership, click on reset cookie and supply the details when asked to get that membership working on that computer (providing that computer accepts cookies).
