Sorry if this is a newbie question. I've not done my research.
If I want to drastically change the appearance and have new types of navigation on the
site and what not, I think I can do that but I need to update that template or theme every
time there's an update to the Mediawiki software - this is what I had learned a while
ago but it may not be true any longer.
Or is there an easier way to plugin a theme and have it work even after updates? Is this
the right thing to check out?
