I see that recently i didn't see all the notifications i receive in my forum. I've read that if you have a huge number of unread notifications you have issues. I have 2 addons that create daily notifications by mass tagging users so it depends maybe on this...
There are a way to remove these unread notifications to resolve the issue? @Brogan
@Mike i have an addon that permits to tag an entire group (of 400 members). I use to tag these members daily to get their attention. I have many inactive members so i think that have many unread notifications can create a performance issue, i'm right?
I have also one mass alert addon and a Credits Addon that give credits (with alerts) every day.
I'm unclear if you're reporting an actual problem or just concerned about the number of alerts. I would say unless you're having an issue, you shouldn't really worry about it; the data won't really be used. That said, tagging users that haven't visited in months (for example) isn't likely to be useful since they won't be made aware of that.
I report a problem, i didn't receive all the alerts...example, on my forum sometimes happen than a user reply on a discussion that i joined, i didn't see any alert that inform me of that. Some users reported the same issue.
So i thought that maybe the problem are generated by the massive number of unread alerts...see this post by Kier that said that have a huge number of unread alerts can create performance issues.
