The GWAS Catalog is committed to providing support for users. We have improved the documentation on our website, extended the process documentation, and FAQ have been added (www.ebi.ac.uk/gwas/docs/faq). The helpdesk provides rapid responses (48 h) to emails and support requests via gwas-info@ebi.ac.uk, announces major updates from the announce list, and tweets from the GWAS Catalog Twitter account (@GWASCatalog). During the past year we have also delivered our first face-to-face training workshops (training materials available at ftp://ftp.ebi.ac.uk/pub/databases/gwas/training_materials/).
