First, I think it would be best to get in touch with holybanana or hexii, who will be able to give us admin rights on IVAN Sourceforge. I don't know Finnish, but Hexii seems to have an active blog
here... Even if he has no time for development, that should be just 5 minutes for him. (Probably better to create those Sourceforge accounts first, so he will know whom to give them.)
We need it for two things. First, to update the website to include our forum. And second, a version control system such as CVS is in practice essential for joint development. (If you don't know what a version control system is: when you do something new to IVAN, you issue a single command ("commit" ) and your change goes to the repository. If you do another single command ("update" ), your local copy is updated to include all the changes committed by everyone else.) We could create a new repository somewhere, but I think it would be much better to use the official IVAN CVS repository. This will make us official.
I hope they won't feel bad about passing official IVAN development to others.
Also we should choose: which ones of the unofficial modifications go to our initial version?
