Social media OAUTH plugins

[Kathy Reid]

Hi everyone,

First of all, a huge thanks to the WP Melb administrators for setting up this site and mailing list - fantastic initiative.

At Deakin University we run an enterprise grade blogging service, http://blogs.deakin.edu.au.
We'd like to expand this service offering by allowing OAUTH(2) authentication for external members to post comments.

Would anyone have recommendations for which plugins would be best?

Any advice or information much appreciated,

Kind regards,
Kathy
