take your notepad and code for nukes.
It has amazed me for so long how there has been a void out there for a good open java cms/portal app that doesnt suck! especially considering how many goofy php apps of this type are out there (sorry, im no fan of php). to take it into a full blown groupware app would be excellent.
I havent really used OGO yet, but i understand it is integrated with openoffice.org, maybe another good idea for down the road.
