Yes, I post a lot of tutorials on my websites since it is a good way of getting a lot of traffic and back links from people who quote your work or use search engines to find tutorials.
I have posted guide for people who were either too lazy, or too stupid to actually look around the forum before jumping to the conclusion that it was about Twilight..
I'm thinking about making a tutorial on how to post and reply on forums since I ran into a few people in the past which never used forums, and have troubles using phpBB, Invision, Vbulletin, etc forum software.
