I have been using the new beeper. It's life changing. Having all my conversations in just one app is actually making me talk to me friends more.
It's great!
Fuck iMessage though. Don't know why people give such a shit.
I don't believe there's a wait list anymore. You should be able to just download it from an app store for free. In the future, they'll release a premium version that will require payment.
I have an invite link that may get you in faster. Let me know if you want it and I'll send it to you in a direct message. I've already sent it to @UntitledQuitting@reddthat.com
