I want to change the text that currently says "log in" on my drupal site.
It is built on drupal 7 on a sub theme of omega. I have made a hook to the login block by following some instructions found here: http://drupal.org/node/1167712, which basically adds some code into the themes template.php and then making a tpl.php in the templates folder in the theme.
I can get it to put more thing into the login block by this method so i know that its hooking to it properly, just dont know how to change the "value" of the "log in" button.
Try out the String Overrides module. Good for making a few changes here and there.
