Just Joined and re-logged in message

Dolly,
The long description is coming because you've set a URL for the message. With a URL set, Facebook will automatically insert information about the page that the user will go to if they click the link. You can set the specific description you want by using the Open Graph features of JFBConnect. Right now, Open Graph seems to be disabled, so Facebook is simply using your meta description tag. You can enable the Open Graph integration in the Social -> Open Graph tab of JFBConnect. Then, on the page of your site you link to, add the following tag:
{JFBCGraph description=Shorter description to use}

It can take Facebook a few days to recognize the updated text, so you'll have to be patient for the new description to take.

Finally, just so you know, your subscription expired a few days ago. We hope you'll consider re-subscribing again. We normally don't provide fast support to users without active subscriptions, so wanted to let you know.

Hope that all helps, and good luck,
Alex
