My letter was signed on the 13th, mailed (postmarked) on the 16th, delivered on the 17th. If the letter was signed on the 13th, then TFC Thompson probably finished working on it sometime between the 9th or 10th (11 and 12 may were on the weekend). I know a few here noted they received their letters before I got mine, even though they sent them after mine had been received.
