Maybe it has been increased much earlier, but I just noticed today that the quota for PMs is now 100 instead of 50.
Just wanted to say Thank you for that. 
Yes it's a pretty old news. You are welcome though.
after seeing all these free email quotas from all the service providers, i think GS should offer 10,000 PMs atleast
I am running into the same problem again. My inbox keeps filling up and I grudgingly end up deleting some… I demand more space!
NOW!
