PM Message is broken and few others.

I just read a PM from other user and realized that Enter button (to give space between paragraph) is not working there after the reply got posted, even though it works just fine when you write a reply, making it quite messy to read.

Thanks for reporting this, I have just deployed a fix and it should be working now! Along with some other cool features
