I come form non-English-Speaking country, if I am Impolite, I'am sorry first of all.
	I use android to test.
	many games use facebook app to log in, it means you don't create any account or password, just switch to facebook app(or that's a website?) , and click "continue?",  you will create a account to play game, it is just I want, but I don't know how to do this when I use App42.
	from this:http://api.shephertz.com/app42-docs/social-integration-service/
	The first question:
	before running LinkUserFacebookAccount, I don't know userName and accessToken, right?
	and after call UnityCallBack() , I just get a object "response", and I can use it to get userName or fb Access Token,like this : social.GetUserName() or social.GetFacebookAccessToken().
	so, How could I get UserName and AccessToken before running LinkUserFacebookAccount?I don't know the order in sequence by code.
	The sceond question:
	http://blogs.shephertz.com/2014/07/23/empower-app42-unity-app-with-facebook-auth/
	I try to use DoFBOAuthANdGetToken() to log in with facebook, and  code is below:
	        string[ ] perms = new string[2];
	        perms[0] = FBPerms.email;
	        perms[1] = FBPerms.user_friends;
	        App42Log.SetDebug(true);
	        App42API.BuildSocialService( ).DoFBOAuthAndGetToken(fbAppID, perms, true, new UnityCallBack( ));
	But, It open a link "https://api.shephertz.com/facebook/OAuth/" and show "Error Occurred : while Communicating With App42"
	1、why does it show this message?
	2、Before I said, I want to start up facebook app, not a website, how should I make it, or I'm wrong, that's not fb app, just a website?
	thank a lot.
