Centralising and collapse button removal

[pokerie]

Hi there,
Just wondering is there a "quick" way to centralise everything in VB. When I say centralise, I mean so when you log in, the "logging you in" box will be centred on the screen and so will the logged out box. On our forum, we have centralised the logging in box, but have not yet done the logged out box. I'm just wondering is there a quick way to do them all?

And just on the button removal, we've removed the "minimise" button on a few of the main pages, but it's still there on the likes of the "quick reply" box and a few other places throughout the site. Is there a way to disable the minimise feature altogether?

Any feedback would be appreciated
