Hi @iouxo, it is indeed an interesting link, thank you.
In response to your questions:
The ER platform is structured in a way that the participants can create threads and posts, but this could be the space for the general discussion.
There is actually a clear statement, all the material is released under the Creative Commons license but if you wish to find more these are the terms
In general - it is a wiki, but in case of the publication of some of the materials, the contributors will be credited with their ER id, unless they want a full name credit.
Potentially, never. While there are people interested to participate, we will keep the project open. It does have its asynchronous pace too. But, in the meantime, we are working on future events and meetings and will promote them as soon as they have a defined shape.
