Welcome to archisage!
take some time and look around the site. archisage is built on a social network platform specifically for architects but along with regular 'social network' features it also allows you to start your own blog, participate in the discussion forum, organize events and much more. As one of the early members, you have a chance to shape this network. send me a message if you have any suggestions.
Welcome again and don't forget to invite a few architect friends to join this growing community.
