It seems to be a very busy area so please watch for muggles emerging from all directions !
The Fine Pair series was originally started by wizardsmum.
If anybody would like to place 'A Fine Pair' of their own please do, I would just ask that you let mattd2k at firstname.lastname@example.org know first so he can keep track of the numbers and names to avoid duplication.
He also keeps a public Bookmark List of this series so once your cache is published please contact him via his profile page to have yours added.
