hi there
totally new to xwiki - but looks awesome: few questions regarding the featureset
can i invite some colleagues to the wiki via email - to a certain wiki-page?
can i send them t he link
do they need to login to edit the wiki or is it as easy as the invitiation with Miro, conceptboard etc.
and besides this: Does the wiki use the same markup like the githubwiki
look forward to hear from you
Hello @fsj-digital,
Thanks for the interest 
XWiki has an invitation mechanism provided by default. But if you are thinking of a mechanism to give access to a single page using a “private link”, I’m not aware of such think (but it could be provided by an extension).
XWiki support several markup languages. The default one is the XWiki syntax, but Markdown can be installed, and a GitHub-Flavored CommonMark Syntax extension exists.
many thanks for the quick answer and for all your ideas and thoughts you share.
Xwiki looks pretty impressive.
regards
