Hi there, hello.
Is there a manual on tagging somewhere?
I wanted to do a tag, but I can only make it show up in the "general" list, while the tag I wanted to do is for a character.

See the upper menu, there's a "Tags" section. Or go to this link:

rule34.xxx/index.php?page=tags&s=list

Then, search for the tag, and when you find it, use "edit". There, you can change it from "general" to "character".

Thanks!
