Also, if you start to type a forum members name into a PM, it will give a list of names that you can complete it with.
A-Z search capabilities would be useful.
I actually missed when you could sort by join date. That was always fun to see who joined when, how new a member was (more for transaction checking), and just because it was interesting to see. Probably more useful for some of us old time forum members (I feel old!) who remember a member who has been less active and you know who they are, but can’t quite remember what their name was. I usually have to hunt through old threads now to find the names of older members, since some have similar names to other members. 😛
