Congratulations to db3034 on his First to Find. I kind of suspected he would not be able to resist such a FIne Pair as this, seeing as it was him who pointed it out to me in the first place!
The Fine Pair Series was originally started by Wizardsmum but is now managed by mattd2k.
If anyone would like to place a Fine Pair of their own, they are very welcome. Just visit www.afinepair.co.uk to request a unique number and avoid any duplication.
mattd2k also keeps a public Bookmark list of the series. Once your Fine Pair cache is published please email him via firstname.lastname@example.org to have yours added.
