Just asking

Is the guild closed? Do we wait for lvl. 50 to apply?

There’s a community chat channel that we’re all in, but I’d go ahead and apply and even jump in Discord and they’ll add you to the in game chat, there’s an invite thread in Discord

To add to Stache’s comment; pop into the main Discord channel, and ask. You should then get a link sent to you that you can click on to submit your request. It’s the easiest way if you have Discord available.

And no, you don’t need to be level 50.
