Better mechanism to notify community administrators/owners of new requests for membership.
Currently there is a link to review if new membership request were submitted, but community owner needs to regularly check on it and if he forgets to do that he doesn't seem to be notified about the new requests, which is a real problem.
A sample of a real-case scenario is when the Admin is the owner of all the communities. He would need to spend much of his time every day to go through all the links of all the groups he owns, and this is a realistic scenario. Good solution IMO would be to have a notification or a number embedded in the menu link "My Network" in the case new requests for community membership (or friendsip) are pending, something similar like the messages plugin has (a number of new messages embedded in the menu link for messages).
