And thank you for diving in and making some good-quality changes right away.
One thing that might make your editing a bit easier: when you code an internal link, the first character (but only the first character) can be either uppercase or lowercase. Thus, you don't need to code "[[Transgender|transgender]]" - simply coding "[[transgender]]" will work exactly the same way.
If there's anything that puzzles you about the wiki, please don't hesitate to ask me or any other moderator for help.
