Definitely edit your post and remove your email. Firstly that's always a really bad idea, to post your actual email address on a public site, and second that's not how we operate here.
1. Food goes into whatever meal you select. I'm not sure what your problem is, exactly? It defaults to the last meal you chose so every time you change meal you'll have to reselect that meal, but then further foods entered will go into that meal without you having to specify it each time. "Can't it just catch itunder the group I entered it in?" - huh? You didn't enter it in "a group". You enter foods on the tracker page and it can't possibly psychically guess which meal you wanted - you don't go to a meal and click an "add food to this meal" button to start with, so this comment doesn't make any sense.
2. You mean in a food you created? There's an "edit manually entered foods" option in the Favorites tab on the food tracker.
3. If you leave the little tickbox under your post, above the "post message" button ticked, you will receive an email whenever someone responds to the post with a link to bring you back here.
