Kindly is often misused in such expressions as "You are kindly requested to recommend a compositor." Undoubtedly the idea of kindness is attached to the recommendation not to the request and the sentence should be so framed as to express it.
Last is often misused for latest. "The last number of the paper" is not the one that appeared this morning but the one that finally closes publication.
Latter applies only to the last of two. If a longer series than two is referred to, say the last.
