I am considering starting a wiki project for an academic niche. I've already started prototyping using Gitit, I've written a bit easy pages to get a feel for the software and am planning to start working on the most important page that summarises the topic itself, which I believe will help guide me to which pages to create first.

Now, here I'm asking for general advice to a newcomer n00bie wiki admin like me: what to expect, what software, etc. Any advice welcome, but I'll list a few questions below:

• What wiki software? I am liking Gitit, it is nice and easy to set up, and comes with its own server which I run with a systemctl user unit in the background. I tried Oddmuse but couldn't get it to work with a simple server; Ikiwiki setup is too clumsy for my liking (it friggin put stuff on my $HOME by default!); I want to avoid PHP stuff in general; I want a simple wiki that serves simple HTML pages.

• How to defend against spam? My plan is to keep it invite-only for as long as I can. IDK how to do that with Gitit yet.

• How to serve it securely and for cheap, once I decide to publish? It probably won't ever grow beyond a few dozens of megabytes in file size.

• How do you go about promoting a wiki?

• What peripheral services (issue tracker, mailing list, IRC/Discord/etc channels) go well with a wiki?

• What tools are available to ensure content quality (no plagiarism, enforce conventions, monitor changes, ...)?
