It'd be nice to not have to log into webmail periodically to clean out that box, but they don't let you turn the spam filters off anymore so stuff still shows up there. Being able to check and delete from MWP would be great.
On my mail host, for example, I can check "username" and "username/spam" to clear spam boxes. I'm hoping for (but frankly not expecting) something like that.
"Leave Earthlink" isn't an option yet; I need to leave that account open while managing an estate. Believe me, I'll be more than happy to drop it once I know I don't need it anymore!

Thanks!
