Don't know the quota of Admins here,

but seems that Ryan need to increase it.

When trying to send a PM to Ryan I get this errors:

The following errors were found:
         

The member ryan cannot receive any new messages

   

This personal message has not been sent

Thanks for letting me know. Looks like there was a limit set in there, and I went ahead and removed that so hopefully it works now.

At which point exactly does it simply explode?

ryan's inbox? Probably daily
