Login Free PSD
White-on-transparent will be hard to read unless you’re very careful when choosing the background color. Still, it looks cool.
Login Free PSD is a free design resource made by Dribbble user Logoswish / Maxim. As far as I can tell, its license is Unknown.
Helpful hint: Dribbble users are nice. If the license is unknown, it is usually because they forgot to mention it explicitly; not because they were being stingy. Ask nicely and they will probably allow you to use it.
