How you can contribute
Option #1: The easiest way: leave a comment after an article. You can enter your comment on the "discussion" page, (see the tab above the article heading)where it will be treated like a comment. You have to "create account" before you can contribute. Sign your contribution by typing 4 tildes - those squiggles on the upper left of your keyboard. The "discussion" page makes sense if your contribution/criticism/argument is general, and not related to any particular point in the article. Or if you don't want to spend time figuring out how to incorporate your idea into the main article.
Option #2: Make non-controversial minor corrections in the main article. If you see a place in the article itself where your contribution seems to fit in, you can add it there. If you think your contribution should be obvious to anybody and agreeable to everybody, such as a typo or some other obvious error, you can just go ahead and make it in the body of the article, and either sign or not with the 4 tildes.
Option #3: Add an indented paragraph at the spot you have something to say about. If your contribution is distinct from the viewpoint of the article, you can distinguish it by indenting it as a separate paragraph. To indent, type a colon (:) at the beginning of your paragraph. Then you could begin your paragraph with a word describing what type of contribution it is. For example, Objection, Criticism, Friendly Amendment, Argument, Correction, Clarification, Rebuttal, Additional point. Sign at the end with 4 tildes.
Option #4: Create a whole new section in an article. If your contribution is a major point, and/or more than a paragraph, you may want to put it under a separate heading. You could use a word like those just suggested, or you could make up a headline that describes your point. Put two equals signs on either side of your heading to make it a major heading. Put three equals signs on either side of it to make it a sub-heading. (Please sign your contribution with 4 tildes.)
Option #5: Create a whole new article. Just type your article headline in "search", click "search", and an empty page appears with your headline. If you post articles elsewhere, you can "mirror" them here too, and link each article to its mirror. The two kinds of formats complement each other: a blog post preserves the original version, while the Wiki invites more reader feedback where quality is encouraged by (1) the prohibition of ad hominem attacks,, (2) the possibility of very specific feedback by posting it next to the subject matter referred to; (3) the interaction with other readers, with the option of keeping contributions distinct or of merging comments to eliminate redundancy, or both.
