Tag Fairies have a snarky sense of humour....and they do visit!

Poor Kimmar has had her original tags changed, her post count re-set to zero, her tags turned upside down, her dare accepted by the TF (hence her current smiley of tongue stuck to the pole) and still going....

Snark works for Kimmar...I don't think I've seen anyone else change their tags as much as Kimmar seems to manage it.
Me? I just posted food porn, lots of it...and just asked for my tags to include the


smilies.
