Database may need to be recreated!

[Jackywathy]

I made emails unique in the db so it may or may not work

good idea putting this up!

I know definitely for the comments and profile pics, it needs to be updated because I added a new field for the Comments table

just if anyone is wondering how to recreate the database, you just have to run python db/db_create.py once, before you can run python server.py as normal each time again :D
