RelayTo is a newly launched service from the same guys that brought you short.ie, and looks really useful. A interesting extension I can immediately think of is for you to be able to register an alternative twitter account with them instead of having to following @RelayTo, that way I could get them to register say “maci”, and then just get the guys from the model club to follow @maci, and we could all direct message each other without having to allow everyone using @RelayTo to also direct message us.
