SIGN-UP should be first and big, because you want to acquire new customers, Sign-in is for regulars, used to the interface (upper-right corner), they know exactly where it is and most probable a cookie is giving them access anyway. 

A great example of this is Digital Ocean homepage

i have downloaded some svg icons form the web which are all outlined paths. In illustrator i would like to make those paths thicker. Is there a way to do this? I know when a line is still in stroke-mode you can just adjust the size of the stroke, but once this has been converted to outlines i don't know if this is still possible?

thx
