I thought it might be helpful to have a master list of topics that query tracker members would be able/willing to answer questions on if anyone needs to do research. If I can have one of the mods sticky this, then it'll stay at the top for easy reference. Members can PM me with areas that they'd be willing to help with and I'll add them to the master list.
I'll start with me

Edit: Decided it would be easier to put them in alphabetical order...
Amanda dl: I teach foreign policy and international relations... have specializations also in the Middle East and North Africa (politics, (some) history, foreign relations).... know pretty well from spending a lot of time there both Sudan and Lebanon.... have spent a bit of time (enough for some questions) in Egypt, Turkey, Jordan, Morocco...
also I was born, grew up in, and now live near Washington DC, so I know its streets, social life etc to some extent. Also I've seen university politics and carryings-on for many years so the Ivory Tower stuff I can do.
also my adorable husband is a mathematician and knows a lot about physics as well.

Elknutswife: I'm pretty good with history (European, Russian, Egyptian) Marie Antoinette, Catherine the Great, Elizabeth I (I know a lot about Henry VIII, etc) Lucrezia Borgia, etc, studied China and Japan a bit but mostly European countries), mythology (classical, Norse, Egyptian, etc), Pompeii/Herculaneum (the cities that were buried by a volcano) silent film, poetry, hula dancing, NICU (early birth type stuff) lived in Hawaii for a year and was engaged to a gorgeous Samoan for a few months and he taught me how to open a coconut with a stick, climb a palm tree, spear fish, cook a pig in the sand, tattooing the ancient way (did a paper on that) ....all kinds of fun islandy stuff, lived in the south for several years, anything hunting, gun or bow related, construction or remodeling related, or managing a restaurant I could ask Mr. Elky about.
Emjohns: Both my husband and I are elementary school teachers. So teaching, public education, anything kids might say/do/think/go through under the age of 12. I know some older kids too, but am not as ingrained in their culture as I am in the 12-and-under category. I can't believe I'm going to admit this, but I was in the band for years. I can still play two instruments. *The shame!* So music, etc. PTI. Husband can help with anything sports.
Gypsygurl: worked as a flight attendant for two years (have experienced a blown engine, rapid decompression, and had a plane fill with smoke and had to emergency land and evacuate on the runway...also know
a lot about Federal Aviation Regulations, caving experience (worked as a guide for 2+ years and worked on digs), has crossed the country on Greyhound, basic backpacking knowledge. I have a couple friends who are archaeologists and one who's a firefighter who would most likely love to answer any questions about those topics. (I'm sure I'll add more as I think of things..)

MarvaD: was a programmer/tech writer for years, worked for several years in the State Court system in Oregon, knowledge on how the courts function--mostly from the POV of how courts use computer systems (ans: poorly).

MissJava: I have a music degree, specifically with band. Can share about autism (my son has it). Life on a grain farm in Iowa.

Patrick: I spent a few years in the Army guarding the "wall" in Germany before it came down. There's computer and internet stuff. Raising kids as a single father.
Reallyrosie: Though I am betting there are lots of English majors on the board, I would say my areas of expertise are 19th century lit, particularly Austen/Brontes/Eliot, and all things Shakespeare. I am also a high school teacher, former editor/feature writer, did a book for teens on body image, though I'm not as up to date on those issues as I was several years ago. I'm pretty good on the whole teen world/teenspeak--my sons are 21, 16, and 14. Been around education a long time and have a very good sense of a high school culture. I love antiques and collectibles, vintage film--I'm strong on this, by the way, and clothing and design. I have some rudimentary sewing knowledge, but clothing only, not crafts. Finally, as a born and bred Jersey girl, I have a weirdly eclectic knowledge of my too-often-trashed little state, particularly Jersey shore stuff.
Hope I can help!
