@MJ I'll just create an issue for you so you don't have to worry about it.
For future reference, though:
You go to https://github.com/nodebb/nodebb/issues and click on "New Issue". If you don't already have an account it will ask you to create one, then you can report an issue.
The new issue: https://github.com/NodeBB/NodeBB/issues/7300pitaj created this issue in NodeBB/NodeBB closed Recent page has a "Log in to post" button even when guests can post #7300
