I totally agree with some of the things Viper is saying and without question, the user group IS your clan list. The general and SL can mass pm them with important messages. On the other hand I know many SL and general's that are using the silver tag thing as a sort of clan/friends list, but obviously no overlord and stuff like that. they can quickly send messages about clan practice or the clan meeting time for tonight changed or stuff like that. Also, some members don't have a pc or have to use a friends pc to check their pm's but can only do it once or twice a week, this way they can look at the silver "clan tag" and get up to the minute messages, see who is on line right now that they can game with, etc. The people using it have found it very convenient, but they still insist that their members be active on the forums and in their user group. The silver tag should definitely not be intended to be a "clan" or encourage members to not get in their proper user group, it's just a way to quickly see who's on xbl right now in your clan and to have meetings and practices and stuff.
