This plugin allows you to have people register on your blog and takes that same information to register them also on your vanilla forums. It's automatic for them.
I am using the free open source version of vanilla forums and this set up with some reading and common sense. Nobody has tried to sell me anything and the plugin works as intended with the open source version of Vanilla.
You will also need the JSConnect plugin from Vanilla forums Plugin page for single sign on. Setting this up is pretty self explanatory.
A great plugin.
Before you think plugin is broken, make sure the issue isn't your host. If you are getting "Couldn't find a Vanilla Forum at this url :/", it has to do with your server and access to curl. This post at the Vanilla Forum explains it best:
This plugin is only an attempt to get you to sign up and should say so before downloading. I am so sick of these that I have just created an account to start giving feedback ( I know that I should have been doing all along for the benefits of the community but I am lazy by nature ). Don't download unless you want to sign up...
