On Monday, July 26, the SDCC sent out an announcement about the availability of Overleaf as a facility service.
The service is available to users within CSI and Physics who have contributed to purchasing the licenses, not as

or contact the SDCC for more information. Apologies for this significant omission.

The license cost is very reasonable, and if your group is interested, please contact us to request licenses and/or
