Multisite Signup and Autologin

Hello,

I have question about default signup process of wpmu with "remove email verfification" plugin.

After I register and create my blog I'm getting a thank you page "Congratulations! Your new blog is ready!", where I see access data and two links to go to my website or to admin area. After going to my new created website or admin I'm automatically logged in.

This is a process I know from wpmu installations I was working with, but I have few other installations where after registration and clicking on "go to admin" I'm redirected to login page.

Why this is happening? The plugin has no configuration panel, so It should work in one way.

Best regards,
Damian
