Still in Alpha, but gaining momentum fast, is the Microsoft UK Partner Community - Online.
"The Partner Community is a group of networks set up and managed by individuals, partner organisations and Microsoft employees. Our vision is to enable partners to communicate, share and connect with other partners and with Microsoft so we can all do business more effectively and efficiently. The Partner Community will offer many opportunities to leverage information and exchange news, thoughts and feedback - you can even set up your own community or blog"
The partner community is made up of three parts:
Partner Community Home The Community Home acts as a 'hub' to all the partner networks and users within the community. From this page, users can navigate to and explore the different communities.
Networks A network is an individual 'community site', containing the typical features and functionality that is used to provide a network service, eg discussion groups and blogs. A user can be a member of as many networks as they choose. Networks can be set up and managed either by Microsoft partners or by Microsoft employees.
My Home This is a personal site that allows individuals to have an online presence in the networks and the community. My Home provides network service functionality for that user alone - this might include a blog and personal discussion groups for example, along with the ability to set up lists of friends and colleagues.
