Hey guys, I made another plugin for Gravatar signup, though this one is a little different then others. First version was made before Gravatar Box and update of Gravatar Signup but it never got public because comment with download link never appeared on post on WLTC.
Now I rewritten most of the plugin code and added new options.

What you think of it? Are there any grammar or language style errors (I'm not a native English speaker)?

Also there is one problem I found. Two strings aren't translated with gettext even though they are in po/mo files. First one is text of message (line 71) which is made only on activation (line 93) and later is saved in database. Second is URL to locale version of Gravatar (line 58). In both cases untranslated strings are shown.

Does anyone know what is problem with them?
