When members can answer questions on the staff's behalf when we are away, and tag when they are unaware of the answer. My staff and I all, unfortunately, have extremely close time zones, making it difficult for us to be online during the evenings, thus I tend to appreciate members who help new members find their way around the site on our behalf. Naturally, I mean this in a positive light where they only answer questions they know the answer too and are willing to tag the appropriate staff should it be required. These are also the ones who step down once they notice a staff member present to provide answers. As stated, for myself this is extremely helpful on account of conflicting time zones, thus my reasoning for appreciating it.
