I am unable to tag members on my site who's username has only 2 characters. Also, the suggestion box seems a little slow and sluggish when appearing. Suggestions should appear soon as you type the second character of someone's username. It would also be good to have a permission for this so Admins can set how they'd like the tag to function. Tagging should also work in profiles. Anyway to fix this or will this be sorted in the next release?
