Have it so that we can have "PokeBase E-Mail"
Let me make this more clear: This isn't suggesting that we get real E-Mail, but merely a way to send someone a message on their profile or something instead of commenting and have the chance that they won't look at it, or waiting forever in Chat for them to come on. The reason for this is so that some people can send other people messages without real E-Mail, because they don't have it or they don't want other people to know it, or whatever. It's kinda like Mike's PM'ing idea but you don't have to both be there at the same time.
Let's say I want to send user1 a message, telling him that I'm going to be gone for a week or whatever. Instead of writing it in my profile, when they might not look at it, I can send them a "message" and when they next come on there can be a pop-up saying You have a new message that way they'll have to look at it or at least know they have a message.
Now I'm sure many of you don't need this, but to some people it might come of use :)
