How many postcards can I send?

Initially you can send 5 postcards. As you exchange more postcards with other members of the site, the number of postcards that you can send (that is, have simultaneously traveling) will increase. This system encourages new users to try out the project while allowing more avid members to send more postcards.

Your limit will start to increase (from 5 to 6) immediately after you have your first 5 postcards registered by their receivers. From then onwards, for every 10 postcards that you have sent, the number of postcards that you can send will increase by 1 up to 35 postcards. After that, for every multiple of 50 postcards (sent), you will be allowed to send one more.
In other words:

If you have sent between 0 and 4 postcards, you can send 5 postcards.
If you have sent between 5 and 14 postcards, you can send 6 postcards.
If you have sent between 15 and 24 postcards, you can send 7 postcards.
If you have sent between 25 and 34 postcards, you can send 8 postcards.
If you have sent between 35 and 49 postcards, you can send 9 postcards.
If you have sent between 50 and 99 postcards, you can send 10 postcards.
If you have sent between 100 and 149 postcards, you can send 11 postcards.
If you have sent between 150 and 199 postcards, you can send 12 postcards.
... and so on, in increments of 1 postcard for each 50 you send.

This means that if, for example, you have sent 21 postcards, you can have at most 7 postcards traveling simultaneously to other members.

Once you have reached your limit, the only way to free up a slot to send another postcard is to either have a postcard you have sent be registered or have a postcard you have sent time out (expire) in transit. Postcards expire after traveling 60 days although they can still be (and often are) registered after that time frame.

The limit of postcards traveling at the same time stops growing at 100 postcards.

Note: Adjustments to these limits may occur in the future.
