    I’m trying to add the last.fm for wordpress widget but I have no idea how this is done. None of the tutorials I’ve read online are helping. Help, please?

    The blog I need help with is: (visible only to logged in users)

    In general, the code most widgets use is not allowed here at wordpress.COM due to security concerns.

    If you post the code here between backticks we can take a look at it. If it is flash, then it might be possible to use the gigya shortcode to embed it. We need to see the code first though.
