It seems to fork a group chat to a new group on Ameythst.
I'd really like to figure out the group chat so I can help pioneer the move from Telegram for the nostr:nprofile1qqsww0ncvgjvdxzzzraplst3f5v2zcuq2eg8szmre5uu5zgp8npwmnqpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsfzqadl group.
Any advice is welcome.
Amethyst doesn't support NIP-29 groups yet.
In 0xchat, choose NIP-29 groups when you go to create one. 
We moved nostr:nprofile1qqsyxdugekdevmr0vhs0mv7s89vqzqk9sxuy2lewp8hyeg3rffe77zgpy9mhxue69uhhyetvv9ujumr90p5kuem5dahxy6t5vdhkjm3wdaexwtcpzemhxue69uhkvun9v4ehqet9vd5zucmpwdsj7qg4waehxw309aex2mrp0yhxgctdw4eju6t09ugw247z to nostr a bit ago. We still have a group that is stuck on Telegram but we've had decent participation for the NIP-29 group through nostr:nprofile1qqs9ajjs5p904ml92evlkayppdpx2n3zdrq6ejnw2wqphxrzmd62swspzemhxue69uhhyetvv9ujuvrcvd5xzapwvdhk6qgdwaehxw309aukzcn49ekk2qghwaehxw309aex2mrp0yh8x6tpd4ehgu3wvdhk6ynf30t.
