^mountain goat is totally correct, please only use "start conversation" to send messages privately to members. Otherwise, profile posts are publicly viewable, so definitely do not post sensitive information using that method. In the event that you do, delete the post or contact me to delete it.
As of last week the side window showing "New Profile Posts" has been removed from the main page of the Ukulele Underground Forum. It's still available using the navigation tabs at the top, but at least it's no longer a constant feed on the home page.
Thanks for all the input everyone! Please continue to let us know if you have any concerns or suggestions.
