Make It Easy To Reply

Never end your post with something like "Please send your reply to myemail@email.com". If you can't be bothered to take even the few seconds required to come back and check your thread, we can't be bothered to take even a few seconds to think about your problem. On forums, asking for a reply by e-mail is outright rude, unless you believe the information may be sensitive (and somebody will, for some unknown reason, let you but not the whole forum know it). If you want an e-mail copy when somebody replies in the thread use the "subscribe to this thread" option.

Most of us believe solving problems should be a public, transparent process during which a first try at an answer can and should be corrected if someone more knowledgeable notices that it is incomplete or incorrect. Also, helpers get some of their reward for being respondents from being seen to be competent and knowledgeable by their peers.

When you ask for a private reply, you are disrupting both the process and the reward. Don't do this. It's the respondent's choice whether to reply privately - and if he does, it's usually because he thinks the question is too ill-formed or obvious to be interesting to others...
