From https://www.aspermyability.com/post/alice-is-missing-tips-tricks:

Also, encourage the players to have their voicemail tie into their secret, but leave a substantial amount. I tell players to take their time but to try and record about a two-minute message.

Click this link to create a Discord server with channels set up for playing Alice is Missing: https://discord.com/template/T3DSB5HTKVmf

Invite the players to the Discord server, and ask them to change their server nickname to match their character name. Doing so helps make the game more immersive, and means that people don't have to remember which character other people are playing.

Ask about lines and veils. Create a message listing them in the #group_chat channel, then pin that message. Do the same in the #ooc_chatter channel.

SoundFX can be used to play them in Discord.

Upload the files before the game.
