The whole concept of the website only requires a small amount of essential information from each member.

Note that other members can ONLY see your username, the rest of your information is hidden.
Here’s a quick overview of what they will be used for:

Email:

• To create a profile.
• To receive news - if wanted.

Location:

• To make sure people are in the same place when inviting people to become members. 

Country and post-code:

• To show your welcome message in the right category (country).
• Used in statistics to show progress of the project.

You can quit anytime, and your data will be fully deleted right away.
You do need to be invited again if you want to re-join.
