-* ~~Policy page support.~~
-* ~~User agreement in a separate file rather than directly in settings.~~
-* ~~Support all customizations that were done with the EMinds instance of Venice.~~
-* ~~Gitea-like status page showing Go-specific internals.~~
-* ~~Build static Tailwind CSS file rather than using remote-loaded version. (Gate on debug/prod flag)~~
-* ~~Rate limiter.~~
-* ~~Better logging configuration.~~
-
 ## Immediate Cleanups Required

-* A better way to set up the database than `setup/database.sql`. Bring the table setup into the application somehow.
-  The [migrate](https://github.com/golang-migrate/migrate) library might be of use here.
-* Database format migrations.

-
-* Conference Aliases are effectively in a system-wide namespace. Should be per-community.

 ## Additional Items

+* Ensure design is responsive enough that we can use the site on mobile devices.
 * Decouple from MySQL, introduce other database support. Postgres and SQLite are the two priorities here.
 * Fix password storage. Straight SHA-1 hashes aren't gonna cut it. There are better ways.
