My b2evolution Version: 3.3.1

I'm building a website with symfony framework. However I don't like their blog plugins. I've been b2evo user for 2+ years and love it. I'm thinking about using b2evo as the blog and I'm looking into integrating it with the website.

The problem is login. It'd be a pain asking user to remember 2 logins and login 2x to use the website. It'd be great if user login one site automatically logs into the other and same with changing passwords.

I found an [url=http://forums.b2evolution.net/viewtopic.php?t=12395&start=0&postdays=0&postorder=asc&highlight=integration+login]old thread[/url] which is what I'm looking for. Since it was for V1 of b2evo, I thought I should start a new thread and see if there are any improvements in V3 or any new features that can be used. I tried to look at the API docs (as suggested in the thread) but am a bit lost where to start.
