Hi Torrey. I'm not quite sure what you're asking, exactly? Are you asking if random people can just post events on the calendar? No. You have to have an account on the message boards to post something, and whatever is posted is subject to review/deletion. I'll have to check the settings, but I think you have to be a CCA member to post things to the events calendar. I'll have to ask for clarification from the board as to whom they want to be able to post events.
If you're asking about posting public news events (like the date the Fountainbleau in Las Vegas is going to open), I think that would be fine. I wouldn't delete it, personally.
If I totally misunderstood what you're asking, please accept my apologies and reword your question and I'll take another stab at it.
Also, I would LOVE it if you would sign up for an account and post this question in the General Discussion area of the message boards. Go here to visit the message boards: https://forum.ccgtcc.com and click the "Sign Up" link at the top.
