Member groups don't need to be added as of yet, There are only 2 people on board. Once the server, I assume, is released there will be more.

Global Mod crown is the classic one and if you change it into something newer or more modern you'll need to change the others.

You can change the Theme yourself.

As for the "Welcome" suggestion, I agree. Buy don't make it "Welcome", make it something like "Hellos and Goodbyes".
