It isnt a good idea to put your email on a public forum, since there are bots that troll looking for ppl to spam. In general, most ppl are not going to email a stranger with an answer just because someone doesnt want to take the time to check back here, since it could set them up to be spammed.
When you make a post, you can set it as a favorite, and then set in your preferences that you want replies to your favs emailed to you.
