Note: This fest is unrelated to HP Soulmates Fest on Twitter.

Just want to let everyone know about this.

There are currently two HP fests that are called HP Soulmates Fest, one on Tumblr and one on Twitter. They are unaffiliated with one another and are organised by different people. See here for a statement from hp-soulmates Tumblr Group.

hp-soulmates Tumblr Group had its first run in 2022. See here for their 2022 AO3 Collection. The mods are planning for a 2023 fest later this year, schedule pending. (Edited: Prompting will begin on May 14.) Their fest will run exclusively on Tumblr and AO3.

hpsoulmatesfest Twitter Group started in March of 2023, and this is their first run. They are currently accepting prompts. This fest will run on Twitter and AO3.

To avoid any confusion, I'll refer to them as HP Soulmates Fest Tumblr Group and HP Soulmates Fest Twitter Group from now on.
