The idea is pretty straight forward. I didn't see a related topic.
The idea would be to add a section to the user's profile where they can enter a list of canned replies. Canned replies would consist of things like:
Welcome to StackOverflow! We are a question and answer site, not a code-writing service. Please read stackoverflow.com/about to learn how to write effective questions.
(Borrowed the above from StackOverflow user @Blazemonger)
Next to the
add comment button, there could be a second option for
canned reply that has a drop down error which allows you to select one of your canned replies.
The goal would be to encourage the use of friendlier replies to new users, as opposed to trying to compose a well mannered response on the fly each time.
