Using HTML 
You can use just about any HTML tag without a problem. You can add HTML if there is no TWiki equivalent, for example, write 
<strike>deleted text</strike> to get 
deleted text.

 There are a few usability and technical considerations to keep in mind: 
-  On collaboration pages, it's better not to use HTML, but to use TWiki shorthand instead - this keeps the text uncluttered and easy to edit.
  -  If you use HTML use XHTML 1.0 Transitional syntax.
  -  
 Script tags may be filtered out, at the discretion of your TWiki administrator.
 
 
Recommendations when pasting HTML from other sources: 
-  Copy only text between 
<body> and </body> tags.
  -  Remove all empty lines. TWiki inserts 
<p /> paragraph tags on empty lines, which causes problems if done between HTML tags that do not allow paragraph tags, like for example between table tags.
  -  Remove leading spaces. TWiki might interpret some text as lists.
  -  Do not span a tag over more than one line. TWiki requires that the opening and closing angle brackets - 
<...> - of an HTML tag are on the same line, or the tag will be broken.
  -  In your HTML editing program, save without hard line breaks on text wrap.
 
 

 TWiki converts shorthand notation to HTML for display. To copy a fully marked-up page, simply view the source in your browser and save the contents. If you need to save HTML frequently, you may want to check out
