just for those of you who have not figgured it out yet:
when you edit a post you MUST add something to the first "edit notes" field (this will not show up in the final post)
due to some sort of glitch you do not get told that the note is required until you try to repost your edited post, but by that time the original post text has been blanked out in the editor after you hit the post button and you need to use the back button to return to the FIRST instance of the edit post screen in order to make your changes. (dont forget to add an edit note in the first edit notes box)
process:
click edit
make changes
add note
click post.
if you mess up:
click edit
make changes
forget note
click post
screen refreshes with blank post field and red text next to notes field stating it is required
hit back button
reedit post
add notes
hit post
