Just wanted to report that I'm seeing folks having difficulty with likes not completing, PMs not sending, and being unable to post or reply to threads, intermittently. I've experienced difficulties with the like function and when filling out a PM to send, the addressee isn't filling out, so I can't send. I'm using Google Chrome on Windows 8. One person had limited success with shutting the browser down and restarting. I don't know what OS or browsers anyone else is using.
