We should probably add a section/page to document the existing teams, their purpose, and the process to join them. This came up in python/core-workflow#458 (comment) too.

I might also suggest refining the team description a touch, perhaps along the lines of "Mention [...] for help with the finer points of English technical writing," to avoid sounding like its just for people who need basic help with English and to reduce any shame someone might feel asking us for help. Indeed, while some may need it more and others less, almost anyone's writing could potentially benefit from a second look by a proofreader—English technical writing may happen to be an area of strength for me, but I certainly still make plenty of mistakes and typos, and could word things more clearly.
