While I'm thinking about it... has anyone written some sort of admin plugin that would give users an 'update fade' message box on their dashboard page when they log in?
Would that be too annoying? It seems like a nice way to highlight important changes. It might be cool to have an admin page where you could set and/or manage alerts... or how about this? -- an option to alert users one time about something... say, if they log in after some arbitrary date. After that, they're considered notified, and they don't get zapped again until there's another important message.
Just a thought, anyway. I've searched around and found no such thing. If school wasn't about to start back up, I might make it my first plugin project! (It doesn't seem too hard, right?) As it is, I'm about to be slammed... :(
