Very easy. Make a post in "Tech Talk". Use FAQ in the subject line. Then write up your FAQ and post it. Members will review the post and check it for accuracy, post any flaws they see, add information, etc. You'll need to edit your original post to add additional pertinent information and correct any flaws. When the post is deemed accurate and error free by our members and the original author, please PM a Beamter to get the thread moved to the Tech FAQ forum. When the thread gets moved, we will remove all the responses and leave just the original post.
Simple, right?
Please use a format similar to this one:

Cause:
How to fix:
Other categories can be added as you see fit, this is just a general template. See the existing FAQs for a starting point if you're unsure.
