Adium Help: Sending to offline contacts

[Hls811]

I've been using Adium for a few days and so far the only annoyance I have si that when I send to someone offline (or online but invisible) I get a message saying "The contact you have sent a message too if offline, how do you want to send your message" and you have the optiont o not send, send later or send now.

I get this every time I send the message - is there a way to disable this? or always have it 'send now'?

thanks!
