I signed up and sent my application and i think it was succsesfully passed, but when i join the server it says im GLOBAL, how do I become a player?

That means you are a member good sir!

but it says i cant talk

Try typing the following: /CH L

Try talking then and it may say "nobody hears you" That's just an alternative to the global chat, which doesnt seem to be working, so when you've done that, try global again by typing: /CH G

That helped me once.

It wont let me open chests or anything like that. how do I know if i am a member

that doesnt work either

Some chests don't open because there Not Yours! So unless you made the chests, do be suprised if you can't open it. What does it say when you try to talk, It might help if we know what it says <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>
