Submit to Trackers only when logged in

I've closed the possibility for non-logged in users to submit something to the Trackers (Bugs, Features, Patches & Support).
I'm all for everyone being able to submit, but when there's no information about the submitter, it's very hard to respond to it and the items stay open, even if there really resolved. So excuse me for restricting access to logged in users only, but I feel it will enhance the quality of service.
