When I go to click on the custom rank it says change rank but it's not working please HELP!!!!

 Go into the server and check it. If that doesn't work wait a bit then try again?

 I just checked your inventory, your custom rank is not yet complete and should be within about 24 hours. Just check your inventory tommorow

 I might sound like a noob and stupid but I do I check my rank in The Dalek mod universe public?

 Ok thanks

 Type something in the chat. E.g : 'Hi' it should say what your rank is but like Mew said wait 24h as the rank is not complete 

 It said that I would get a notification but I haven't got one and it has been 24 hours so I don't know what to do?

I just got home and was about to contact you. I need more details for your custom rank. All you said was "beta tester".
I need a rank title and colors you want used for it

 So you want me to tell you what rank I am and what colours? I don't really understand when you mean colours and I think when you say rank title you mean the name right? Also how do I tell you the details?

You have to tell him what you want the rank to be called, and what colors you want it to be.

You can find minecraft color codes here

You should be able to contact 1WTC via email or discord, but I can't speak for him, and he would be able to tell you the best way to get in touch with him

 Thank you

 What is 1WTC's email address?

 Actually scratch that.

spicy was right you need to find minecraft color codes and tell him which color and what you want to rank....

 Please Don't necropost.
