[Plugin: SB Welcome Email Editor] How to do a basic translation/default text

Hello.

Thanks for a great plugin!

I need to change the default text-areas, ex: “blog_name Your username and password” to something else, for all my sites – using WPMU. I tried to edit the plugin file, but I did not succeed. Ho can I change the text-values globally?
