I appended the following to the password reset URL in my translations (Spanish / Dutch) of the welcome email to make it a bit more user friendly:

?lang=es&l=###LOGIN###

This improvement for the Spanish translation will cause the password reset to be in the right language and with the username field pre-set with the correct value.

For customer ease I proxied LC to another URL with standard SSL port. Would be nice if LC would provide a custom URL setting for this, just like exists for phpmyadmin.
