The official RexiMemo Discord server is discord.gg/K5mKWvaruF. It is used for community discussion as well as normal support when you need a staff member to look into an account, migration, or site problem.
Discord is optional for ordinary RexiMemo website and Flipnote Studio use, although linking a Discord account naturally requires membership in the server. Keep passwords, API keys, session cookies, migration files, and other private credentials out of public channels.
