At some point we decided to just have one global Sandbox. I think this is fine, I'm just concerned about all the links to old sandboxes that may confuse users, new and old alike.
When I'm not logged in, and viewing the Sandbox, I can see about 7 "Related" questions that also look like sandboxes:
They all link to the current Sandbox (unless you have the rep to see them). Despite this linking, it still seems like it could be misleading to users who are looking for the official Sandbox (we are constantly telling new users to "go to the Sandbox first, etc.").
Is there a way we can truly delete those old sandboxes so they don't show up?
(Is there any reason to keep them?)
