Agreed pgupta, it isn't great. Hovever, you can delete all your text (and hence effectively your post) leaving only a full stop as a 'minimum data set'.

Folks, here's what's going on: we discovered that there's no way (at this time) to separate people's ability to delete single posts from the ability to delete entire threads that they've begun. It WAS in response to the Rudi/SF thread being deleted. The decision was made, therefore, to disable both abilities. People can still edit their posts, thankfully.
I would have preferred a public announcement of the change, along wth a call for comments or opinions, but let this serve as a belated one.
