• If some material is already published another licence, how does it combine with the wiki licence ?

There should be a page on open source licences and advice on how to choose the licence according to the needs of the publisher, with somes examples of licences and wind projects.

By default, the CC Attribution Share-Alike 4.0 International applies.

• Is that alright to advertise some projects on the wiki ?

We think as long as it is informative it is ok to write about projects. However it should not be used for agressive advertising that would disadvantage other members/projects.

• Should the wiki talk about the “how-to” or just be an encyclopedia linking to sources of knowledge?

We tend to think that in order to avoid competition between the members, the wiki should be a web that makes connections between the concepts and send to the different manuals/resources, to let the possibility to the authors to get rewarded for their hard work. This does not prevent the authors from publishing their work on the wiki if this is their wish.
