Mod update notification does not work?

[Black Tiger]

Maybe the problem is on my side, maybe not.

I was not online for some time but I have several mods installed.
Today I came back and discovered that several mods were updated (Like the post thankyou hack, Ibank, Welcome headers) but I dit not get an email about the update.

Do the authors need to push a button to send the update notice to everybody or is this happening automatically when updating the file attachment?

Nevertheless, I've got 5 or 6 mods which are updated now and not a single notification of update was send. Some time ago this worked perfectly, I didn't even had to be subscribed to the thread, only have the "mark installed" button pushed, which I did.

How can I fix this? Or must this be fixed by the vbulletin.org?
