Typically the fourth week of each month, we run an open office hours session. The videoconference is open to anyone interested in QMC at any career stage, including students. Questions & discussion at any level about QMCPACK and QMC are welcome: requests for general advice, tutorials, installation help, questions on QMC fundamentals, collaborations, contributions etc.
The office hours presently alternate between mornings and afternoons to maximize the ability of people of attend. They can be rescheduled to suit your availability on request.
Office hours are run in addition to offering support via GitHub issues, the QMCPACK Google Group, and direct developer contact.
