+_Special text strings expand on the fly to display user data or system info_
-<table border="1">
+TWikiVariables are text strings - `%VARIABLE%` - that expand into content whenever a page is opened. When a topic is rendered for viewing, `VARIABLES` are replaced by data, either user-entered, or info automatically generated by TWiki (like the date, or the current username). There are predefined variables, and Preference variables that you configure. You can also define custom variables, with new names and values.
+
+## <a name="Predefined Variables"></a> Predefined Variables
+
+Most predefined variables return values that were either set in the <code>**lib/twiki.cfg**</code> file, when TWiki was installed, or taken from server info (like current username, or date and time). Many of the variables let you format the appearance of the display results.
+
+- %T% **Take the time to thoroughly read through ALL preference variables.** If you actively configure your site, review variables periodically. They cover a wide range of functions, and it can be easy to miss the one perfect variable for something you have in mind. For example, see <code>**%INCLUDINGTOPIC%**</code>, <code>**%INCLUDE%**</code>, and the mighty <code>**%SEARCH%**</code>.

+- You can add your own Preference Variables for us across an entire site or a single web, using the standard [[Preferences syntax|Main/WebHome#SettingPrefs]]. Whatever you include in your Variable will be expanded on display, exactly as if it had been entered directly. You can place formatted text, page links, image paths.
-- Preferences variables ( on site-level, web-level and user level ) are defined by bullet lines with this syntax:
- - `Set VARIABLENAME = value`
-- Additional preferences variables can be defined on all three level as needed. Example:
- - `Set MYLOGO = %PUBURLPATH%/%MAINWEB%/LogoTopic/logo.gif`
+> **Example: Create a custom logo variable the %WEB% web**
+>
+> <br />
+>
+> - To place a logo anywhere in a web by typing <code>**%MYLOGO%**</code>, define the Variable on the web's [[WebPreferences]] page, and upload a logo file, ex: `mylogo.gif`. You can upload by [[attaching the file|Main/FileAttachment]] to [[WebPreferences]], or, to avoid clutter, to any other topic in the same web, ex: `LogoTopic`:
+> - <code>**Set MYLOGO = %PUBURL%/TWiki/LogoTopic/mylogo.gif**</code>
