* Here's GPG policy :
|
|
* By default, all pgpg keys imported via a RS user (make friend and accept friend action) are signed at level 0.
|
|
* All signed keys by RS are set to be trusted marginally. You can change it to full or no trust in the friend profile
|
|
* For a key to be marginaly valid, it has to be signed by one fully trusted key, or at least by 3 marginally trusted keys.
|
|
* All keys that have at least marginal validity are designed as valid in RS. They are shown in the RS gui in order to be signed.
|
|
* If there is no validity then the key is not shown.
