You can start shortening your URLs right away. To integrate with SpeedBlog, goto http://bit.ly/a/account and make a note of the API key.
Setting up SpeedBlog for bit.ly
To setup SpeedBlog integration with bit.ly, login as host into your DotNetNuke portal, go to the SpeedBlog Settings and type in your bit.ly account (username) and the API key
Using shorter URLs
If you’ve setup everything correctly, SpeedBlog will automatically use the shorter URLs wherever the number of characters in a link is at a premium. SpeedBlog will also automatically default to generating URLs for custom domains if you have a Pro account. You can also use the shorter url in your custom Theme template by using the <%= SpeedBlog_ShortURL%> variable substitution tag in your .ascx control file.
A small but important note: The bit.ly settings are common to an entire portal so if you’re using SpeedBlog on multiple portals, you may need to do this step multiple times. All blogs within a portal share the same bit.ly account settings.
