How do I sign up for TS5 beta testing?
You can’t currently. Signups ended quite some time ago.
Like @EnigmaPatrick said, you can’t sign up for the beta at the moment, but you can follow Teamspeak at their Social Media Accounts because they are posting Codes for the Beta. You can reedem them on beta.teamspeak.com
You can’t these days. You can still get some keys from teamspeak’s instagram page tho
Not just Instagram, we hide them in Facebook and Twitter posts as well.
This is correct, they’ll be a new way of getting beta access soon, I can’t at the moment however, say more.
