Hey Brett, It is becoming more and more of a rewrite ;-)

As I said in one of my earlier mails, I am adding a 'task' system to the IO engine. One of the always present tasks could be.... delivering an event. Easier, more transparent, developer friendly.... Or should I make it a Pro feature ;-) (I won't) > > What do you think? I'm prepared to be told that I've missed something > crucial and valuable :) You haven't. You made my to be implemented list longer, but this is very valuable to all of us. It may take some time to get this done, but I'll get there. --Maarten -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with "unsubscribe" in the subject, without the quotes.
