The Development Gateway portal provides a space for communities to share experiences on development efforts. The portal supports the Development Gateway Foundation's knowledge-sharing efforts through services such as an online directory for information on development projects (AiDA), an electronic procurement market (dgMarket), information on major development topics (Topic Pages), and links to a growing network of country-level initiatives (Country Gateways). By offering users virtual interactive communities centered on development issues, the portal's Topic Pages encourage knowledge-sharing and help improve collaboration among development practitioners. Expert guides and global topic advisors work with their communities to highlight the most relevant and useful resources available on the Internet. The topic pages enable you to share knowledge and locate resources on a variety of development topics; build a community of experience around development topics through individual member contributions; receive free email alerts and newsletters; and make connections with thousands of registered users
