(BTW: you can edit your post (How do I change/delete my post?) to use What shortcuts can I use for linking to other information? (like [id://1059438] and [id://840731] to link to specific nodes), so the links are valid/clickable)

(edit: fix link to What shortcuts can I use for linking to other information?)
