Moved to the General Advice subforum, since you're asking about the writing process.
For the record, once something's posted to the mainsite, it's considered finished work. At that point, no one is obligated to give you any more feedback than their vote.
A sandbox page is kept on the sandbox wiki, and drafts you write up there should be shown to the IRC chat and/or the drafts forums for feedback before a mainsite post.
Furthermore, if you're aware that there are spelling errors, please fix them up yourself before asking people to look over your work. Basic spelling errors make a piece look really sloppy, and less people will want to look at it if it seems like you didn't bother putting minimal effort in.
(and you don't need to sign your posts, this is a forum thread, not an email.)
