Scheduled for resolution No information about how to add links to signatures

I see some folks have links but I can t make mine work. Have links in the signatures been disabled for some reason?
See also https://www.diyaudio.com/community/...-platform-feedback-wanted.380360/post-6883882 and https://www.diyaudio.com/community/account/upgrades. As you can probably tell, I am very unhappy about these new rules. I payed for a "lifetime" membership two months ago, and now this membership allows less links than even the most basic membership as it was before the software upgrade.
