Anyone know any nice sliding login/reg plugin that will works WordPress 3.4.X?
I tried this one but it has a few errors, i don’t think the developer will be updating it.

Maybe this one could be fixed?
It looks like a good starting point, but i can’t repair it myself
Or how can i build it if one is not available? it’s a neat login display.
