For a long time people have been asking me how to put links like this in my articles. I would explain that all you have to do is highlight the text you wish to turn into a link and click the little "chainlink" icon where you would input your URL. Well I have finally figured out why this was not working for them. It turns out the JU has different editors for users who are ranked as "Power User" and higher. Level one folks don't get to use this "chainlink" button (the entire toolbar doesn't even appear on their editor) so their links don't work the same way.
A side effect of this is that this "new and improved" WYSIWYG editor has a non-functional "pure HTML" mode (as demonstrated here). This was how I posted everything as a level one user and now I can't which sucks because the "better" editor has no spell checker. Thusly I only use the JU editor for short articles (like this one).
