Is it really so difficult to automate the search for those posters who can't be trusted to do it for themselves (similar to the way excerpting requirements are detected/enforced)? Or, at least, put a link to the Search function on the Post page?
Given all the improvements I've seen here over the years, this one seems like a no-brainer.
The mod's requested that several times. I don't know all details, that's John's area. All we are asking is to do a search before posting.
