The report lists only some of the new features, new data and other improvements that we have added to Ensembl since our last report (14). Users interested in the most up-to-date details of the Ensembl project should visit the Ensembl main page (http://www.ensembl.org) and follow the ‘What's new’ link and/or subscribe to the low-volume ‘Ensembl announce’ mailing list by sending email ‘subscribe ensembl-announce’ as the message body to majordomo@ebi.ac.uk. There is also an Ensembl blog (http://ensembl.blogspot.com/) and associated RSS feeds which in particular cover upcoming Ensembl training courses around the world (see below). Users with questions about Ensembl can consult the extensive online help, FAQ and tutorial materials (15) (include animated tutorials) or contact the Ensembl helpdesk through the website or by emailing helpdesk@ensembl.org.
