I don't know how the system works that send an E-mail when you get a pm, but would it be possible to include the message, or at least just who it's from, in the E-mail?
I check my e-mail from my phone probably 20 times a day.
Live journal shows me the message, tells me who sent it, and gives me the option to reply right from the E-mail. That's flippin amazing.
Myspace at least tells me who it's from. Some messages can wait, others are a little more important, and just jumping at every message sucks.
It it workable?
