Test ... can I c&p in a certain domain, as plain text?
https://www.******.com/account/knowl...wn-Domain.html
Hmm (editing this after I saved my reply): I entered it as plain text, not enclosed in url /url tags, but the forum software (a) enclosed it, and (b) removed all the domain name part between "www." and ".com".
When I explicitly attempted to add it as a link, the forum software accepted what I provided then - when I saved the text - changed it:
https://www.******.com/account/knowl...wn-Domain.html
How odd. Maybe the company represented by that domain had an argument with the person who runs this forum?
