Jeff's Subscriptions is a modified version of Jon Udell's most excellent mySubscriptions script.
To set up your own Subscriptions Macro:
Copy the following code:
Paste the code into a new document in your favorite text editor.
Save this document in your Radio UserLand/Macros folder, as "jtcmysubscriptions.txt".
Now to use this Favorites Macro:
Copy the following code:
Paste the code where ever you want (in your posts and/or templates).
This macro can also be implemented as a Web Service.
Special Thanks to Dictionary.com for showing me how to distribute code snippets without the recipient unintentionally picking up invisible characters which render the code inoperable.
