I don’t understand what all the jargons or terms everyone is using. What are wikis, why set up a community, what is Fandom University, how do I really get started. I watched the video for getting started but they are talking about things I know nothing about. ALso, I am searching for answers to How can I change the text size for the website? It is very small. Also, I chose the dark mode and someone wrote in dark text so I could hardly see it. Shouldn’t the gadget that creates the dark mode also change the text colors to be appropriate for dark mode? If not then using dark mode is useless. Am I wrong, please explain.
