There's now a tool called "visual editing" that lets you edit in plaintext without all the complicated syntax. When you go to the editing page for any article, it's in the top right of the text box. I use it a lot - it's just so, so much easier than the old way.

Wikipedia does not allow original research. It must reflect what is published in reliable sources. If misinformation exists in what Wikipedia deems to be reliable sources, it can exist on Wikipedia.

For what it's worth, there's a list maintained by editors of most sources and whether or not they are reliable. If you think they're wrong on something, make an account and join the conversation!
