Okay you guys, I've reached Level 4 (which some of you suggested will be the solution) but STILL can NOT reply to messages received. Any other ideas? (I 'contacted' Agnostic.com via their 'Contact Us' function a few minutes ago.)
Your "level" has Nothing to do with it! Are you scrolling a bit to have the "reply" box show? And clicking 8n it to activate it so you can start typing?
Check your settings... Allow members to contact you and you to contact them.. I guarantee that's the issue..
