Last I remember, everyone wanted an invitation to the group, I told you all to contact me, and nobody did. I'm not developing JavaOp on my own, even if I did have time, so someone needs to step up and join the development team. Contact me (see my profile) or reply here for information on the sourceforge project.
Incidentally, somebody is working on JavaOp3, and has been for awhile. So you might not want to spend a whole lot of time on this.
Who is "somebody"?
I only know his AIM handle, I don't know which name, if any, he goes by elsewhere.
