Acronyms and abbreviations are tracked and linked by redirect. The redirect page itself is placed into Category:Abbreviations.
If two or more different meanings for the abbreviations exist, there would have to be a disambiguation page instead of the redirect.
Redirect Example: UEE
#REDIRECT [[United Empire of Earth]] [[Category:Abbreviations]]
To edit a redirect:
Click the page and note the "redirected" line, just under the title. In our examples case that says "(Redirected from UEE)". Click the term after the "from", then select edit (or edit source) on the resulting page.
