We use Slack and Github as our primary tools to work as a group. Join us on the #satrdays-chat channel on the R User Groups Slack to chat.
We have a specific account for Tito that charges 1% commission on tickets due to the community, non-profit nature of the events. Use the slack channel to request access from Dave Parr.
Most event organisers use Mailchimp to build a mailing list of attendees and communicate with them.
Call for Papers
We have an ongoing discount with sessionize.com and will support the use of this with the remaining R Consortium funds for folks to use for their CFPs.
