Categories

Making categories for other folks? Format your data thusly!

Enter one category per line using this format:

Category name: item 1, item 2, item 3

Example:

Turtle species: Loggerhead, Green, Leatherback
Trees: Fir, Pine, Oak
Shapes: Circle, Square, Triangle

Before sharing with others, ROT13 the text using:

rot13.com

Send the text to your pal, they will paste it in the input box and then press "Load Items"

If an item includes commas, escape them like this: \,

So a "Groups of 3" category with A, B, C and 1, 2, 3 as items would appear like

Groups of 3: A\, B\, C, 1\, 2\, 3
