I know if Microsoft does it, it'll be more useful and stable.
But... Err... Does Microsoft do it? I don't think so
. Even there's no contact for Msn Messenger Suggestions at Microsoft...
But with plus, it can be made, and it can be useful...
And also i've tested the stuffplug's "enable talking blocked contact" feature. Yes your messages go when talking a blocked contact, but his/her messages don't come.
