Ok, ther are serious problems with this add-on now.
1. Apparently you can only text yourself.

When I tried to text someone else, I recieved the message myself. THIS IS A VERY MAJOR BUG!!
2. When someone sets up an account with the UPDATED plug-in, he/she cannot send messages at all as it comes up with the warning I quoted in the above post.
I am going back to the previous version until all of these HUGE pre-historic size bugs can be fixed.
(ATTACHED THUMBNAILS) As you can see-- email is enabled, yet my users cannot text me.
