My goodness, I think Dave Tosh was having a bad day.

Yes, the forum cron is having some problem - I'm working on that right now.

Yes, sorry about that, there was some bugs in 1.8 that only occurred when a course was in non-forced visible groups mode. It's all fixed now I think: MDL-8741

Exactly. print_error() is THE way to do all error messages in all new code. It not only prints a nice string in your own language (usually from the error.php language file) but it contains a link to the wiki for more information/feedback etc. I've added this to the coding guide.

If anyone wants to help convert any of the old error() calls to use print_error() instead, we'd love you to help!
