Since anyone can edit almost any Wikipedia article, it is possible for biased, out of date, or incorrect information to be added to Wikipedia. To improve Wikipedia's reliability, fix these problems by doing the following:
As often as you can, monitor and check changes made to articles. Your Watchlist, and the Related changes and Recent changes features are useful for this.
For dubious statements that are not sourced or are likely to be challenged, hunt for references that are reliable, relevant, accurate, objective, and timely. Add citations for these to the article.
Read the references provided by articles and check them for reliability, relevance, accuracy, objectivity, and timeliness. That is, read the source material cited, and remove irrelevant or unreliable citations.
Let's start off with the basics. You can make italics by putting in 2 of these(') before and after the word, in other words, I made the word italics italic by doing this ''italics''. You can also make things bold by using the same method,only this time use 3 's, in other words, I made the word bold bold by doing this '''bold'''. Finally, you can make bold italics by placing 5 's before and after the word or words, in other words, I made the bold italics bold and italic by doing this '''''bold italics'''''.
