Maybe you all have tried this, but here is how I got mine to finally update.
When you go to the blogrolling.com/ping site then scroll down to the 'double url form'
Type in your blog name, then the site of your blog and then on the 'URL to publish' line put in: www.revgalblogpals.blogspot.com
My apologies if you know this already and are using your favorite cuss word on me right now. :)
