What to write about
Create a profile
Prefer the /build wizard after you sign in. Use this email if you need a row taken down or cannot recover the account.
Find engineers
You have a capability-shaped role and want to talk through the index, or a shortlist once accounts exist.
Corrections
Something in an entry is wrong, out of date, or should be taken down. Say which page, and it gets fixed.
Replies are written by a person, so they are not instant. Messages about corrections and removals are handled first.
