Hi team!
I just failed to send a PM and I thought you might want to know. I failed for 2 reasons:
(1) There was apparently invalid HTML in my response - but ALL I did was type in the editor.
(...
I have seen the very same behaviour (e.g. on first submit of message an "invalid HTML" warning and any subsequent posting attempts failing with a flood protection warning) when posting a normal reply here on Atlas. This seems to have started with the 20.10 upgrade of Atlas.
