Eric from MyBlogLog just pinged me about an important item that I know is relevant to a number of my readers. The MyBlogLog join buttons many have in their sidebars.
Unfortunately some people decided to abuse things a little using Iframes and the join link, thus MBL were forced to switch the links off.
Things have now been fixed to require confirmation.
For those using existing buttons, you will need to change the URL because the join URL has changed.
You can pick up the new URL at the bottom of the widget page.
