The IntelliJ guys send me a new IntelliJ registration key for open
source projects for a year.
The old one will expire soon.
IANAL, but any drools team member can use it as much as he likes for
open source work only, as far as I know.
I 've forwarded it to mark.
Send me a mail if you want me to forward it to you too.
With kind regards,
Geoffrey De Smet
