You can quickly and easily add additional links to any Humanities Commons Group by putting links into the Group Description section of your group. There’s currently no wysiwyg editor for that field so you have to type in good old HTML for it but it renders the HTML links clickable when saved and loaded.
The image below shows how it renders the links on the right side of the page, simply follow the format for a standard HTML link and save it. Multiple links can be seperated by a blank line in the editor (no <br> or <p> tags needed).
You can add a link to anything using this method… Google Drive or other external to HCommons storage, chat tools such as Microsoft Teams or Slack, brainstorming/visualization tools like Miro, etc!
