Diggz is a completely free of charge
service. You can post your room, or listing to find a roommate free of charge. You are able to interact with others via the 'like' button (unlimited) to indicate interest and you get 5 Instant Messages to speed up things with top prospects.
We do provide the option to purchase more Instant Messages. This is recommended if you are on a time crunch, or want to introduce yourself with a personal message instead of a generic Like.
