Many times new members come and make comments and there are times I would prefer to talk to them privately about it but can not due so due to the PM limitations.
In fact just recently a friend of mine joined and we wanted to chat privately but could not do so until he made 10?(not sure of this is the exact number needed) useless posts.
Is there any particular reason for this?
All I can think of is , it is to stop people from joining just to harass members. But in all honesty if they made an account just to harass someone there is nothing stopping them from spamming 10 useless posts so he can use the PM feature.
