Getting around CloudFlare to open and edit own forum threads on LET
Opening up a thread (plus editing it) and perhaps posting a comment in a certain way on this site will result in a protection system called CloudFlare (CF)  to kick in and ask you to complete a CAPTCHA challenge  before allowing the post to be accepted by the forum system. It has to be said that I have not identified the "certain ways" definitively which certainly trigger CF but I think posts that have links and listing of computer commands on them might influence such a behaviour. Unfortunately, the integration between LET forum system and CF is rather broken in the sense that once we click "post/submit" on the thread submission page, we will be presented with an erroneous CF CAPTCHA challenge which renders the whole page kaput.
Identify ways we can disable and enable JS at will using either browser settings or extensions. Since I know that Firefox has a wide-ranging selections of extensions, I opted for the latter. I installed the NoScript extension  .
After installation, go to LET. By default, NoScript is set to disable JS on all sites, so we need to enable it until we get to the post submission page. Click on the "S" icon somewhere on the far right side of Firefox address bar (in my case it is just beside the Options menu ["three horizontal lines"]), and choose "Allow lowendtalk.com". The page will reload (it will do this every time we change from Allow to Forbid, and vice versa). Login to LET and head to "New Discussion".
Here we need to disable JS once more. Click the "S" icon and choose "Forbid lowendtalk.com". We will be presented with a basic version of the page with text manipulation buttons not working at all. Set the category, the discussion title and the post contents. We can use external programs that provide in-browser or offline Markdown editors such as StackEdit  to format our post. Once done, click "Post discussion".
Instead of the broken CF popup we will get if we had JS turned on, we will now be taken to a basic (and non-working as well) CF CAPTCHA challenge page. Here, we re-enable the JS ("Allow lowendtalk.com"), and in trying to automatically refresh the page, the browser will ask you to confirm the re-submission of the page (the contents of our post). Allow/OK it, and the CF page will reload normally. Solve the challenge, and we will then find that our post has been successfully submitted.
To edit the forum post, follow the same steps. Please ensure you have JS turned on first before wishing to edit it as the Edit menu is only visible from JS script menu.
That is it! Happy posting and I look forward to seeing posts that otherwise would not have been possible due to the CF error.
Have a nice day.
