Avoid a splash screen, they are more for show than they are useful. The login/sign up page should be the first thing the user see's (if they need to log in to access content, i.e Facebook), if the user can access the site without logging in, then do not force them - have the option else where.  So have a dedicated login page.

Do we really need splash screens?

Log In / Sign Up on Splash screen?
The links in the main navigation end without a trailing slash, which do not match the canonical tags which end without.

Is there an easy way to make all links throughout the site end with a trailing slash? Please note. I'm not looking for a redirect to force a trailing slash, I'm looking to get the internal inking to include a trailing slash.

Bit of a Magento beginner, looking for an easyish fix if there is one.
