Re: How do i disable case sensitivity for username?
Yeah, this is an annoyance, and a WordPress thing as opposed to something that can be changed in BP. Users can, of course, case their display names however they like, but the actual login must be lowercase with no non-alpha characters. And Buddypress will only send @notifications to the login name, as opposed to the display name. (In other words, @moddedlife will notify you, but @Justin won’t, and may send a notification to completely the wrong person, if it works at all) I’ve reported other issues surrounding that too, but since the redesign of this site, I can’t find anything, or I’d link to it.
The login/display name thing is suboptimal and potentially very confusing for users, but I don’t know if there are any plans to do anything about it.
