The free Core plugin now assigns a Shor.tt API Key and facilitates the creation of shor.tt links within the WP administration dashboard, or via the use of shortcode.
Full shor.tt statistics are maintained for all created links, and the RESTful API is available outside of WordPress for any reason that floats your boat.
Shor.tt is a quality-controlled domain meaning that you won't be sharing your branding with the cave-dwellers that use such services for nefarious purposes.
We see a lot of brokers use bit.ly, and we wanted to provide a more finance-friendly option.
The new feature will be pushed in version 0.2 of the free plugin due late today.
