appreciate the help and supportSome members of the site don't want public visitor messages, so they turn that feature off... just like some who don't want Private Messages either... we have many features to allow customization of your experience here...
Jahnice is correct, leaving someone a message is easy, try leaving one for me on my profile! Just click my name at the left of this post, and you will see an option to "View Public Profile." And then you should be able to see the message box... and type something in...
