I've made 2 updates to the Notifications feature:

Old Notifications Deleted:
Even though you didn't see the old notifications, they were still there. Apparently the script I made a while back which was suppose to delete old notifications wasn't working so I fixed it. Deleting old notifications should speed up the notifications page and might speed up the rest of the site a tad as well.

Notifications Exceeding 100 will display:
If you go a long time without visiting vizzed, there's a chance that you'll have more than 100 notifications by the time you come back. Before there was no way to see all the notifications if this was the case but now this issue is fixed. If you ever have more than 100 notifications, you'll get to see all of the notifications, even the ones beyond 100. However, if you refresh the notifications page, it'll no longer those notifications beyond the 100 (since notifications beyond 100 get deleted each time you view the notifications page).

Davideo7 : We have been needing this for a while.Thanks.
