Hello,
I think the most important is to have an up to date documentation, so I
favour minimalist options * (the fewer the better)*.
Q1 : I vote for option b) but this is not conflicting with d) proposed by
Thomas.
Q2 : Option a) the default skin.
A comment regarding this draft : I'm not sure that the USERS mailing list is
appropriate to ask for a documentation change. The documentation is a
component of the XWiki software and it must match the features implemented.
So, for me, the DEV mailing list would be quite natural.
