 * 1) I have already stated that there's no such thing as "the" template. Templates can be of great variety, ranging from infoboxes to various widgets and hacks. There's no universal method to build one, but usually either wikitables or HTML code are used.
 * 2) You can add a favicon by clicking the Wordmark tab and using the form in the Favicon section to upload an image in the .ico format.
 * 3) Click the Wordmark tab at the top of the screen; there you can choose between a textual or a graphical wordmark. In the latter case, you can upload an image there.
 * 4) Rollback reverts edits by a certain contributor to a page until the last revision not made by him. If User X were to edit a page ten times in a row, the rollback would revert all of them in one click to the last version not authored by him. See this page for more info.
