New spoiler tags

Ok, so I participate in some internet forums where having 'spoiler' tags is quite useful - the idea being that some of the content is hidden until the reader clicks to show it.

In theory I've enabled it for our posts in this blog, so this post is a test.

» Click to show Spoiler - click again to hide... «

THIS IS THE SPOILER CONTENT
For future reference, this is the code for it:
< div class="spoilertop" onclick="openClose('YOURSPOILERID11')"> » Click to show Spoiler - click again to hide... « < /div>
< div class="spoilermain" id="YOURSPOILERID11" style="display: none;"> THIS IS THE SPOILER CONTENT < /div>

If the test fails of course, then I'll delete this post, and most people will never know it existed...
