In this release, we've added our most requested feature: the ability to delete messages. If you want to delete something you posted, simply long-press it and choose "Delete message." You can also delete any message posted in a board you chair.
The way we've done deletes may seem unusual, so I'll explain our thinking behind it.
When we first built Glassboard, we decided against deletes because we felt "we need to own what we say." We wanted people to be more accountable when they post to Glassboard than when they post in some other places, so we intentionally didn't permit deleting messages.
That was a mistake, because it meant you couldn't delete something you posted to the wrong board, or get rid of something obnoxious someone said in one of your boards, or remove that photo of yourself in drag you uploaded when you meant to share a picture of your cat, etc.
So now you can delete, but we've done deletes in a way that still shows you posted something. Rather than remove a message entirely, we replace its text with "Message deleted by..." and get rid of any attachments. If you delete a message that has comments, the comments aren't deleted because those comments could have valuable information (but you can still delete comments you posted).
The way we've enabled people to delete any message posted in a board they chair reminds me of how a lot of newspaper sites handle comment threads. If someone posts a rude comment, the site's moderator can delete it and have it replaced with, "Comment deleted by the moderator." That way the actual comment is gone but there's still a record that so-and-so posted something offensive. You see that happen enough with the same person, and you learn to ignore stuff they post in the future.
PS: Glassboard 2.3 has a bunch of other changes, too. The Android app has been given a fresh coat of paint, and everything should feel even faster now.
