每日吃瓜

Hi all!
For a big site update it seems we'll have to let go of the private messaging app we used so far, and there doesn't seem to be a good replacement solution.
Question for you all; do you use the PM system often and would you miss it badly?

Never used it, feel no need for it.

Used it a few times, never got any reply.

I have used it quite a bit, and would hate to lose the capability.

Maybe some way to ask for an email address? I would not want my email address to be visible to every web crawler, but would not mind having it be viewable to a selected member or two.
