(1) The preferred way to contact the IGV team is to use the igv-help group. Post help questions, bug reports, feature requests, and suggestions. No need to subscribe to the group if you just want to read postings, but you must subscribe in order to submit your own posts.
(2) Developers who prefer to report bugs and request new features on our source code site, can add issues to our GitHub issue list.
(3) If you need to reach the IGV team privately on other topics you can contact us directly.
