I never see something more ugly in my live :( I am sorry but I look wordpress so powerfull and now when i start use it the must simple think and important is so hard.
I lost 3 days looking for plugins or acceptable ways to create a login / register acceptable, and even now is a time completely lost, almost useless. The most beautiful I've been doing is not working well because it shows user name and access the user dashboard forces rather than just access the profile.
Joomla undoubtedly is much better in this respect.
My rating to Wordpres as related to login / register is zero very big.
I am not a user with big knowledgeable, but I know enough to do well and wordpress has hindered me a lot on the topic of login and registration. I hope they can improve that much better.
