I want my whole community to contribute in the wiki with ease and MediaWiki is such a scary software for them.
Mediawiki is scary for everyone but staff members on your site and the nerds of the nerds that edit wikipedia.
Can you use bbcode with XenCarta?
YES !!! That is a major plus of XenCarta.
Other pluses are the robust caching of templates and the cool templates themselves.
This wiki is entirely template driven: Jaxel's wiki:

You can also embed a wiki item into a forum post. This can be a very powerful thing.
Wiki items have Likes.
- features? Are there any important features missing from XenCarta that are available from other wiki?
Yes there are missing features.
Wiki entries do not have authors, and do not have a "Permission System" - the ability to edit wiki items is either all or none.
One way to really get people interested in the wiki is to give them ownership of wiki items. (ie. I keep the bbcode section of the xenforo wiki up to date, and you keep up the section dealing with all the smiley packs, Joe Blow can keep up the list of Addons related to Wordpress). Ownership is a part of responsibility.
XenCarta, IMO, is designed for mostly admins and few choice members to edit the wiki. That works for Jaxel, but then again his wiki isn't a heavily edited wiki.
There isn't a back end dealing with wiki edit changes (ie. Wiki edits aren't able to show up as "edited" in a Wiki admin's area).
And I don't think you add wiki items from the front end (Not sure, must verify).
Currently there is no integration into the "What's New" aspects of the Forums.
Keep in mind, you might be less picky than I am about wikis

Let us know what is your ussage needs and what you might wish for in a Wiki for Xenforo.
