For those who haven’t tried WP-United 0.9, know it is very rough around the edges. The install instructions are incomplete and the only way to get it is from a source code repository. That being said, there is some promise. The WordPress plugins install on WordPress 3.1 without issue and things seem like they will work. I say seem because I did not have success getting it all working correctly yet. I stumbled on my install a couple of times and ended up with a problem I couldn’t diagnose and so I dropped it and removed the install. I will try again soon.
Part of the problem with 0.9 is its use of Flash in the admin to do some of the updates. It’s not very transparent what is going on so in my case the error I was getting could not be diagnosed. If I have success with my next install, I will detail the steps here.
