Tried to leave a bug report using the Bug Submission Assistant web page (by LibreOffice Help -> Send Feedback). After creating an account and filling in all the fields, and trying all that twice, pressing Submit only ended up with red error message at top of the page: "Data not yet loaded. Please press submit again in a few seconds." Additional minor thing: the webpage layout assumes that user has quite wide browser window - with my normal window width the visual layout is hard to read as the vertical "Get Help" column on the right is mixed over with the main content (this gets fixed when using wide browser window).
