I would like to use the Option 4 in this page to share our reuslts with other group member. Visualizing and sharing results | Tutorial: Using Nextstrain for SARS-CoV-2. However I didnt find any instruction to create the account and how to setup the group. I click the get in touch under the How to get started but it only redicect me to a page of how to run nextstrain analysis for SARS-CoV-2. Could you please help with that?
