I don't have a horse in this race as I did all of my MRs for the year in January. However, here is what I think.

This thread was started with a specific purpose and therefore its title ("Admirals Club", "January", leaving out SNA, etc) is a bit too specialized and out-dated for future needs. The focus on January was in response to the exceptional overlap between DEQAA and DEQ11. Now DEQAA is gone, DEQ11 has been extended to June 30, a new city (SNA) has been added. Someone flying ORD-SNA in May, and with no interest in AC, will most likely not find this thread by searching.

However, as you said, the need to discuss fares, availability, upgrades, who will be on which flight, and what activities could be organized continues, and perhaps it would be best to start a new thread dedicated to DEQ11 promo.

(Experience also suggests it would be best to leave out the matter of guesting people into AC from public discussion. Those who know one another can coordinate privately. I still see a 30-day membership as the best option for most. The best $99 I spent in January.)
