You know, this is a form to post a message to the administrator

I was just messen with you buddy lol...  Question, would i be easier to just add lang value rather than a input for the number and then if we dont need it we can just put none or not available or something as a text default. 

That is very strange indeed.. could be a function call to the core functions that is linked to that class.    The reason i thought of just doing the lang key is that how often is someone going to change their contact phone number, not very.  Just an idea...

In the plugin settings you can select who the mail goes to.  If the email you want is not there then add it as your admin email.   Also please remove your duplicate entries in your post, did you not see that.
