Wrong hyperlink in syntax help

STR:

1. Visit Syntax help (don't ask me how I found that page)
2. Click on official RedCloth textile reference at the bottom of the page
   » Expected: Page with Syntax Help Actual:"Buy Domain ..." 😥

Additional Info:

a) Useful Help can be found at https://textile-lang.com/doc/tables (of course I did not test that all, but for example the Textile Link input (editable) I saw there also works in Crabgrass for "tel:+49...." hyperlinks
b) May be that Syntax help should become a quite normal Wiki page?
