 ### Presents
 Presents are items given to the user when they login, with a little animation (for example, the KOP song was given to the finalists as a present). To add a present, you must insert it into the `mai2_item_present` table. In that table, a NULL version means any version, a NULL user means any user, a NULL start date means always open, and a NULL end date means it never expires. Below is a list of presents one might wish to add:
 
-| Game Version | Item ID | Item Kind | Item Description                                | Present Description                            |
