I have just installed Social Login on this site, some of the authentication services, not surprisingly require a setup process, most of which I have not done.
One All has some good help pages, the following services do not require set up,
Blogger, Hyves, Live Journal, mail.ru, Open ID, Stack Exchange and WordPress
22 May 2013 : Problems testing with WordPress, I have asked for help here…..
4th June : Still stuck with WordPress, now need a WordPress blog owner to test for me. Big help form Claude Schlesser at oneall.com
The setup guidance for Yahoo, Twitter, Google and Facebook are very good easy to follow.
I have configured Disqus, but not yet tested it.
Next to test a raw OA provider; should be fun.
Now on ello.davelevy.info, not yet tested, I am using the same server account for all the subdomains. I copied the parameters.
