Can't reply in my own Dreamweaver forum thread

Adobe tech support counseled me to post a complaint in a new message here in order for the "Dreamweaver forum team" to respond. 

Clicking Post after composing a Reply in threads I created appears to do nothing or causes an error. When I try again, the system accuses me of "flooding" forcing me to wait 3600 seconds (had to get my calculator out, couldnt you just say 1 hour). This has been going on for the last 3 days. My internet connection is strong and Ive had no connectivity issues with my ISP at all. I've been posting on this forum over 10 years, probably much longer. ATM, it appears I can start a new thread ok though (?).

Among the numerous problems:

- I get signed out while composing a message

- When I sign in again and call up the "Saved content" — or paste it in from my own saved version - clicking the Post button gives flooding error.

- "Correct highlighted errors" error, but nothing is highlighted

- Authentication failure

- Invalid html. This in nonsense. Im only replying to a post in a thread I created using the text box provided. But this is a web dev forum, putting css or html in a post shouldnt break it....

I was able to post a test reply using my iPhone. And, when I turned Wifi off then on, I was able to post a reply once, then the errors began happening all over again. 

Troubleshooting:
- Emptying browser cache

- Switching browsers
- Trying again later in the day
- Turning Wifi off/on
- Test posts w iPhone
