I am out of school, but am an intellectually curious autodidact (not a particularly effective one). I was once considered mathematically gifted but fell off the bandwagon early - no encouragement or mentors. Others I know are in a similar position. This is LW, after all..

A bunch of us would be interested in shoring up and increasing our mathematical abilities, and so would be situationally similar to a homeschooler. Should we still contact you? Otherwise, I'll wait for your wiki of resources. Thanks!
