Ok, took a while to update my server and such. Installed the software and configured it a bit.
It currently is on invite only. With anonymous view access.
http://www.interactivio.com
And here's an example basic interactive:
http://www.interactivio.com/display/...teractive+Home
After we get some initial stuff going, I'll slowly expand the publicity of the site. Depending how we like this stuff initially.
The concept is like a wiki, every signed in user will be able to modify interactives, That is. If the author of the story wants that.
This software has a page versioning system on board. That means that if someone edits a chapter you can always see WHAT he changed, and even restore back to one of your earlier versions.
There is also a chat system (lower right corner to communicate with each other)
People can comment on every page.
Integration with youtube and other stuff. As displayed in example interactive.
Make polls ect...
Searching trough interactives
Labels
Favoriting, Keep track of updates on your favorite stories!
Too much to put here, in short. I think this is an even richer system than what writing.com offers already.
The only annoyance is. When you make a new chapter, you will have to edit the previous chapter to link to the new one...
