First of all Congratulations on 17 years, that's an awesome feat. When @Apparition(my Co-Leader for our weekly iMSR) pointed this post out to me. We discussed and decided not to run back to back raids on this Friday but instead we will run our usual iMSR at 7:30-8ish EST(right after last daily Hami run), To Help you celebrate your occasion and instead of a second run we will send our league which is filled with friends and regulars, to join your event.
Anniversaries come but once a year, but there are many Fridays to be had, plus Torchbearer is but a small playground, and I know competing for the same people to play with is not that easy on a small server.
Great job on 17 years, may you have many more and hope to see you at some of your events.
