The 'L' on a Neighbourly member's profile picture refers to 'Learner' and indicates that this neighbour is temporary verified.
Some Neighbourly members have access to Neighbourly before completing their verification - when waiting for their verification document to be approved, or when they've changed address.
Temporary verified members can post, contribute to discussions and send and receive private messages, however they cannot see the addresses of other members in their neighbourhood until they are verified.
Once a member completes their address verification, the 'L' will disappear.
