Messenger

Facebook Messenger was the official chat platform of COMMUNISM from 2014 until 2016.
History
Historically, The WIDEVERSE had used forums for text based community, or the very limited chat channels in Mumble. RaidCall was a short lived reprive from those brutal ecosystems, echoing the later development of Discord. However, by 2014 as voice chat had tapered off, talks between the COMMIES became more text based. Originally using Googles messenger, Pigeon eventually moved everyone to Facebook Messenger due to its ease of use and ability to be used mobile, which at the time was a big thing.
Over the next two or so years, most of the active COMMIES would filter in and out of the chats, with several sidechats being made. By the time of the Color Coup though, Taylor had moved most everyone to Discord in late 2015. Pigeon was a notable holdout, which resulted in his increasing separation from the rest of the group. A few of the new COMMIES recruited from BMW, like Peaches, would join though during this time.
By 2016 and The BEEFY Troubles, Taylor had stopped using Messenger all together. Prude was the lone holdout, though after Leaffy blew up on him, he admitted Taylor was right about them and too left.
