Here you can digest how to use Wikipedia in bite-sized morsels. The tips listed below were created for the Tip of the day project, or the Styletips project, but are listed here by title and organized by subject area for your convenience.
When linking an article to a category, you can tell the category how to sort the article alphabetically by using a piped link. For example, [[Category:Baroque composers|Bach, Johann Sebastian]] will alphabetize Johann Sebastian Bach in Category:Baroque composers under B instead of J.
Troubleshooting Wikipedia's look and feel with skins
Wikipedia should function and look right in any web browser. However, depending on the layout of an individual page and the Wikipedia skin set in your User preferences, a page layout might be broken in your browser. If the problem occurs on a single page, edit the page to fix it yourself. If you cannot fix it, put a message on the Talk page for the page (a screenshot always helps!). If the problem occurs on all pages, try a different skin. Your browser might have some minor issues. These are listed at Wikipedia:Browser notes.
