How do I transfer my Unique Identity (ID) to another PC?

Click on "Settings" -> "Identities", then choose the identity you want to export (usually Default) -> click "Export" on the upper right, then choose a filename.

Now on the target PC, go to "Settings" -> "Identities", and choose "Import" then point to the INI file to complete the import process.

This will allow you to receive the same permissions settings assigned to you by the server regardless of which PC you're using.
