posts to help and support on Discourse rejected

[JamButty]

As my last post got no response, I tried to repost it on the help and support section (https://discourse.ubuntu.com/c/support-and-help/306) of the Discourse system. I accessed posting via the " Ready to start a new conversation?" link at the bottom of the page. I know there are limitations for new users, but this is a single standard text only post with no images, which should be permitted even to new users in this category.
Every time I attempt to post, I get "error occurred: Access denied".
It saved to drafts, but will not post. Username there same as here "JamButty".
And yes, there is a similar question up, but the last time I tried to include a similar problem on another's posts as a comment I was chided by administrators for hijacking a post.
