Transfer messages

[jabnet]

Hello, my name is Javi from Spain. I've recently changed to your fantastic guestbook after another great guestbook service have been finished services.

I've found control panel very useful, but I have around fifty messages from old guestbook, and when I have begun post messages, I receive the spam protection message "You have recently posted a message. Please wait a few minuttes and try again. "

I have read this post, but I haven't found an option to disable time check.

Please, show me a way to easily transfer messages, because I'd like to use the service, is very useful and pretty customizable.

Thanks
