@rootsmusic Unfortunately deleting isn't available, but there are a couple of ways to achieve the same thing. You can edit your post to remove the text in it (replace with n/m - "no message"). OR, you can "Report" your post (using the post dropdown menu) and request that a moderator removes it.
As for labels, I have good news! There will be enhanced label functionality being implemented very shortly (including product/version).
There is currently an advanced search as well - on the search screen, there is a small blue link that says "Advanced." You'll be able to access a lot more search functionality there.
