As a former IBM employee I just subscribed myself for the LinkedIn group IBMers. In LinkedIn the standard message showed that my subscription is pending approval. In my email however I received this excellent message from the group owner on LinkedIn. It is an automated message, what makes it stand out from the other messages is at first the fact that a message is being sent while my subscription is in the approval process, most group owners forget to use the power of this option. Secondly the message has excellent content: it tells me exactly what I need to know: a reminder about the purpose of the group and a short description about the process so I know what to expect.
