I use triple X's in my notes to indicate I still have to fill something out.
If you managed to find this site, it means I forgot, and it tried linking you to a subpage literally titled XXX.html.
You can reach out to me and bitch to me that I should fix my website, or you could wait a couple weeks in the hope that I figure it out myself.
In either case, sorry for the inconvenience. Have a consolidation cookie:
