I've been mining with you for just over 4 years. Thank you for the great service and good luck with your future endeavors.
You've got some funny math skills... the announcement post is dated 10/22/2011. The first block with BTC Guild in the coinbase script was 152700 on 11/10/2011. If you're going to make something up, at least make it somewhat credible.
Eleuthria, best of luck to you in your new cardboard mansion

The pool has been public since May of 2011. This announcement post is the 2nd post for the pool. When it changed from Proportional to Pure PPS (and before PPLNS was introduced), we started a brand new thread. BTC Guild mined *thousands* of blocks without a tag in the coinbase, because the old pushpool software we used in the early days didn't have a built in way to add coinbase tags. We were the third oldest still running pool (second oldest if you start measuring from our first block found with the pool software during private testing, but Eligius opened up to the public a few days before BTC Guild).
EDIT: Original forum thread for the pool:

Dust, please accept my apologies. I based my reply on the information I had available, which was quite obviously incorrect. And, I admit, I saw the newbie tag on your account and jumped to conclusions. Again, my apologies to you.
