Thread:Project:Support desk/wikipedia-ish version, restricting new registration

wiki version 1.16.2 php 6 mysql 5

hi,

how do i find a wikipedia-like version of a wiki? see this page for example: Egg_(food) how do i create a table of contents? how do i link references not directly to the reference site, but to the bottom of the page?

how can i restrict the registration of new users? how can i disable creating/editing of not registrated users?

thanks for your help! marc
