Oh right ok, in that case I'll be giving it a try! Now to find some online tutorials, or perhaps I'll buy an ebook...
I was thinking though, wouldn't it be pretty cool if WYSIWYG editors could make a feature of this? There must be loads of people who have similar news snippets which occur on multiple pages of their websites, and if they're using static webpages then they'll undoubtedly have the same problems as me in that they'll have to update every single page in which that news snippet occurs, one at a time.
But since the news snippet menu always contains exactly the same information and format throughout all of the pages in which it occurs, why could you not define this code in all of the pages and ask the WYSIWYG editor to "manage" them. In this way, you only update one of the pages with the new information, and the editor then ripples this change through the other pages where you've previously defined the same code area, therefore automatically updating them and removing the need for the poor old webmaster to go around and manually update them all.
