Virtual Attendance

After the great success of last years all-video conference, we have decided that GRCon will always include Live-streaming and the ability for individuals to participate remotely. This will include the main track as well as the workshops.

This year the Virtual participation for the main track is "Free/Pay what you want", but we are encouraging participants to pay at least $20 to help defray the contract commitments for the video support personnel. We will have live captioning to aid the hearing impaired. Please register so that we can get an accurate count.

We are actively working on improving your Virtual experience. Specific events for Virtual attendees will be highlighted here. If you have suggestions on how we might improve your experience, please write the Organizers at
