Add a links page

**Path to page with content (_do not_ include domain name):** N/a

**What content is incorrect?** There isn't a page with common links

**What should the content say or communicate?**

It would be nice to have a section or page that could link to related projects or sites.

Start by inspecting the website source and its existing page and navigation structure; the issue provides no file path. Done means a links page or section exists and presents the agreed related projects or sites, but the issue does not define the links or exact placement.
