Mendeley - an alternative to BME
Over the past 8 years nearly half a million users have signed up to BME, a platform where scientists can interact and grow their professional networks. In 2013, Elsevier acquired Mendeley , a research collaboration platform with nearly 3 million users worldwide. It offers users the same sharing, networking and collaborating functionalities as BiomedExperts, but within a much larger cross-disciplinary scientific and academic community. Mendeley also has a suite of free, cloud-based tools that helps you to manage your papers and citations, and lets you access your work across all devices.

As a result we have decided to shut down BME and focus our development efforts on Mendeley, which is better positioned to meet the current and future needs of our users.
