Anyone can read the wiki. If you would like to edit it, you must first join the Bogleheads forum. Once you've joined, send a private message requesting access, and you can then become an editor. Information on editing the wiki is available on the left sidebar of every wiki page. Suggestions are welcome by posting in Suggestions for the Wiki.
If you see content in need of improvement
, or a new page on a topic not yet covered, consider becoming an editor so that you can contribute to the site. If you find yourself writing a reply to a forum question that's been discussed a number of times before, consider creating a wiki page with the answer. Then you and others can reply to subsequent questions on that topic with a link and a quote of your text. That way, the Bogleheads Community both preserves our knowledge base and makes it more accessible, particularly to those using search engines.
