1. Posting/commenting gives an error. If you keep trying it will post eventually, but it takes a lot of attempts to do so successfully. Squeaky is working on this.
2. In order to see friend-locked posts (and probably eventually post or do anything else), we have to leave and rejoin the groups with every journal.
3. Journals created after 2/13 have to be re-registered. When you do, there may be some random content in said journal, if that content belongs to a player in this game, please contact them to see if they need it. An example for mine: Helga Hufflepuff's app (played by Valerie) is in Jocelyn Herondale's journal. While our posts from post-2/13 journals are still there, they are no longer attached to them, which means those characters will need to be re-apped.
4. If you have changed your email/password on any journal after 2/13, that has been reverted and will need to be changed again.
5. Renames made after 2/13 have also been reverted back. I believe those tokens (if purchased prior to 2/13) are made available again. If not, you may need to contact Squeaky.
6. Any paid services purchased after 2/13 are gone and will need to be refunded. Squeaky mentioned disputing through PayPal.
If I have forgotten anything, feel free to add it.
