I've read through a lot of those wikihow pages before. Some of them are great. Careful, though, when reading them. It's easy to end up wandering into a less fantastic one. Also, always remember that anyone can edit them, so you should do your own legal (and other) research. I've seen some weird things show up in there, and I've found myself editing to attempt to fix things.
As long as you remember to verify everything on your own, there's some good info to be found.
