The format of StackExchange sites in general discourages the sort of letter-format questions common elsewhere. You know what I'm talking about:
Hi,
I have ${problem}. It has ${details}. Any thoughts?
Thanks in advance, ${username}
Is it OK to use our awesome edit-powers to remove these greetings/signoffs? I say it is OK, as it doesn't affect the meaning of the question, and slots right in next to fixing formatting flubs or interesting spelling.
