At the risk of getting banned, I'd like to express the opinion that I think the PM message limits are unreasonably draconian.
I can get lots of free accounts (gmail etc) where I can store thousands of messages. I can create free web servers with gigabytes of free storage.
I paid for this account and yet I get a limit of 5 PMs. I really think that sucks and probably negatively impacts building a community.
Yes, I understand that a sensible limit needs to be set to manage overheads - but I think it should be hundreds or thousands and not 5 or 50.
What do I know? A lifetime in IT and Engineering including running and administering web services.
Just my opinion, and opinions are like r'soles ... everyone has one.
