I think the purpose of using this thread, to test senior member only security, was a success.
Therefore, I'm closing this thread.
If you Senior Members feel the need for a private thread for some dedicated topic not suitable for the outside world to see, please let me know. If it serves the Senior Member community we'll set one up.
We can add a Senior Member only thread to any forum, but it needs to be something related to Seniors only, like the beta.
Otherwise, there's always the Supporters Forums for discussions for more private conversations.
