(1.) When 4ppl.com server is down it doesn't have an alternate I.P.address that carries the custom "404" message that would say that the server is undergoing maintenance.
(2.) It would be nice if when checking emails if you could see if that user is online, either while viewing the list of emails you have received, or after opening the email and while reading it. Maybe an icon or link to chat with them too.
(3.) Might be nice to have a "Last Time User Logged On" note next to each users profile and/or email.
