I have set up a basic wiki, and I am interested in hiring someone to do some customization. Currently, I am interested in someone doing very basic customization of the wiki; no new extensions need to be created. Rather, I am hoping someone can do some of the following: restrict editing of some pages to certain users, implement a hierarchy of pages (so for example, a page for "San Francisco" is under the hierarchy of "California" and then "United States"), and set up some form of protection against mass deletion of data (so someone can't create an account and then delete everything). There may be some additional work in the future, but this is what most interests me now. The wiki is already up, and it is hosted by SiteGround, so all of the files are accessed through the SiteGround cPanel. There is some information/content on the wiki already, but very little. Overall, it's completely new and doesn't have users yet.
