Chemistry Exchange is user-driven scientific content: you can share, vote, and comment on articles and news among a global community.
It enables a scientific community- create a profile, assign tags (keywords) to your account, and find and network with other registered users. It also functions as an article repository - start a library of scientific research that's important to you--publications you've authored, or articles that furthers your research.
