Here it’s important to differentiate and it’s not so easy to label Zulip as fully trade-free. 1. https://zulip.com/ is NOT trade-free. There are plans that one can subscribe to in the “cloud”: https://zulip.com/plans/#cloud and even in self-hosted version: https://zulip.com/plans/#self-hosted 2. However, there is a “free-community-plan” for certain groups of people (in education or non-profit for example): https://zulip.com/help/self-hosted-billing#free-community-plan

Koinei te take ka tapaina e tetahi ko Zulip he hokohoko-kore mo "Nga kaupapa tuwhera-puna, Rangahau i roto i te waahi matauranga, penei i nga roopu rangahau, nga mahi tahi-whakawhitinga, me era atu, Nga whakahaere e whakahaerehia ana e nga kaiwhakaako takitahi, penei i te ahorangi e whakaako ana i tetahi, neke atu ranei o nga karaehe, Nga hua kore utu kaore he kaimahi utu, Hapori me nga whakahaere whaiaro". Ka tika pea te 3 poraka mo tera?
