I believe it was created by and is supported by Yllus/Sully. He's not part of the staff, but he is an Elite member.
And I suppose, well, no, I guess it's not official. It's not FuseTalk software. However...it's an interface to the FuseTalk software (ie. all credentials are passed to the FuseTalk login script, etc). While it may not be entirely secure (read: the owner could log your information), it seems reliable enough to me. I've used it on a few occasions.
