Hello, for the time being I removed the "Spiders" category you had added. Currently, the wiki doesn't have subcategories of creatures based on taxonomy. Should we start, that should be something discussed and planned at length so it can be applied to all creatures. For example, "Athropods" might better for the function you had intended. I noted it in our discord server, if its something that's agreed on I can add it to our to-do lists.
We still appreciate the interest in contributing and this is an idea worth discussing.
