Yeah, anyone can make edits. Feel free to copy existing articles I've (or others have) posted and use them as a template. It would look a lot better than straight copy and paste entries from Xiclopedia that I've seen on NasWiki.
Some example articles to nab for templates, that you can click Edit on and copy/paste into a new Wiki entry for new articles are as follows. Just try to name your article correctly and existing links to them should work right.
