The Konstrukshon blog has an article about the AECnetwork.

The AEC Network is an informal, free of charge, global network for the construction sector. All are welcome in this network, all we ask (and this is very important) is that members do not spam other members with sales approaches. We would like to foster an atmosphere where people can openly discuss their areas of expertise and look for collaboration and do not want to discourage participation due to unwanted spam.
