So I log into Big Fish and decide to visit the Technical Forum. I get there and find I am now a guest. I am asked to Confirm My Account. I do so.
New page. On the top and the bottom of the "Thank you, MrLipid! Now it's time for fun!" message is this text string: {IS_CONFIRMED?}
And when I go back to the Technical Forum, I am a guest again and asked, again, to Confirm My Account.
It appears there is no way, at the moment, to leave a message on the Forums.
