Thanks for the replies guys.
So I guess I was just being paranoid. I just thought that maybe there should have been a similar minimum post count to be able to send messages, like the minimum posts you need to make to be able to chat for the safety of users. I guess its not feasible though, it would probably dissuade people from participating on Pandy's.
Thanks anyway guys.
I think it might be difficult to include this, because it might prevent new members from contacting staff (mods, section mods, chat mods, team welcome etc) when they first join if they have a question or want to raise a concern in private or something.
If something feels 'off' about a PM, you can always ask a mod and they can look into it for you. If you just don't feel comfortable reading/replying to a member of the board who has PM'ed you, I think it's ok to ignore it - it's ok to have your own boundaries. I think sometimes people either aren't sure how to use to forum and might PM someone by mistake, or might not feel comfortable replying on the board yet, and it might not have occurred to them that they might make someone uncomfortable by receiving a PM from someone they don't even know at all on the board.
I think most times people are trying to be helpful, supportive and friendly. If someone sends you a PM asking for information about you though, or makes you feel uncomfortable in some other way, do refer that to a mod because nobody should be doing that.
