    Thanks for the great plugin and continued support.

    Any plans to support the Short Links for Google Apps as a URL service?

    Hi Gerald, Thanks for the follow up.

    I have an "Enable API access" option for my Short Links settings as well as this sample python script they included in the help section:

    """Example script.
    
       Connects to an installation of Google Short Links and submits an
       API request.
    
       Example commands:
         Get the details of the short link 'foo':
           python api_sample.py
               --details
               --server=shortlinks.example.com
               --hmac=foobar
               --email=anything
               --url=anything
               --shortcut_name=foo
         Create a new short link 'bar' that points to www.google.com and
         is owned by owner@example.com:
           python api_sample.py
               --create
               --server=shortlinks.example.com
               --hmac=foobar

         Create a new public HASHED short link that points to www.google.com and
         is owned by owner@example.com:
           python api_sample.py

    Cool. Thanks for the code snippet... will look into it.

    Do note that implementation will not be within these two months though.. unless time permits.

    Thanks Gerald.

    Is this a hard time limitation or would a financial contribution help bump the priority. Thinking less of a one off donation and more of a "pay for this function" type contribution.

    At this moment, it's more of a time limitation as I am busy with school related assignments.

    Is it of high priority? If it is, drop me an email at contact@fusedthought.com. I'll see I can do anything to help over the weekends...

    Thank you for considering financial contribution (even a little) as it's always appreciated as it goes to pay for textbooks or items for school :)

    Not a rush by any means. Once I get a little closer to needing it I'll follow up with you.

    Regarding financial contribution. You have talent, I have money.. at the end of the day it all balances out :-)
