Kind of a small thing but I figured I'd add it anyway since it's an interesting UX tidbit.
When I get mentioned in a post/reply that is in a forum that I've subscribed to, I get two email notifications for essentially the same item of interest.
Ugh, that's pesky. vB has a lot to answer for. I'll log it with them but that's about as much as I can do as we're cloud hosted.In good news, the plan is to migrate off it as soon as we can. Sorry that I can't be more helpful in the immediate term.
