Downloading the packs
Very soon, you will be able to download libraries allowing you to easily implement OpenID in your site. You will be able to follow the tutorial included in the documentation. Some modules are already available; all you will have to do is to copy them within your site, to make it OpenID compatible.
To be informed of the date when all this will be made possible, send us an email at info[at]oids.org
