Tellervo is free and open source software. While it is not obligatory, we'd really appreciate it if you could tell us that you are using it. Development is largely supported by grants and therefore it is important for us to be able to show that it is useful to the community. If you are willing to leave your email address we may contact you in the future to request a letter of support when we apply for grant funding.

Tellervo has been kindly funded by the Malcolm H. Wiener Foundation; the many patrons of the Aegean Dendrochronology project; the Laboratory of Tree-Ring Research, University of Arizona; and by Cornell University.
