Okay, I think I've figured out that you mean 'mark diary as read', as in one of your faves? Because I tried that and it didn't work for me either. I'm pretty sure Steve has a bunch of bugs and things to work on for the next version of Bloop, and that is one of them.
Yeah that's how it currently works. It will take you to a blank page with the number 1 really small in the top left corner but it does submit your entry to that circle. It's been like that for a while lol
The "mark as read" link hasn't worked for a long time.
The circles taking you to a blank page - has been doing that for a long time, too. It will still submit your entry though, even though it loads as a blank page, or at least use to for me, I've not used the circles for a while though.
