1. Thanks for this plugin, as all your plugins, this is an excellente coded and very useful plugin.
2. Where can I send You the es_ES .po and .mo files?
3. How can I translate every widget? or of they don't have a .po file themselve, where are their files to translate them from the .php file?
Thanks for your time!
P.S.: Please consider to add the Wake Up sleepers plugin to the WordPress repository in order to increase its popularity.
