 				The first time you use GitGitGadget, you need to be added to the list of users with permission to use GitGitGadget (this is a <i>very</i> simple anti-spam measure).
-				Any user who is already on that list can do that, by adding a comment to that Pull Request that says <code>/allow &lt;username&gt;</code> (with your GitHub login name).
+				Using <a src="https://web.libera.chat/#git-devel">IRC</a> or <a src="https://github.com/gitgitgadget/git/pulls?utf8=%E2%9C%93&q=is%3Apr+is%3Aopen+%22%2Fallow%22">PRs</a> you can find a user already on this list and request them to add you to the list.
+				To do so, they simply have to add a comment to that Pull Request that says <code>/allow</name></code>.
