Can't find external solutions to send a MR

What happens

I can’t find external solutions for the challenges with an extension that doesn’t exist in OTHERS.lst.

What do you understand or find about that problem

There are plenty of external solutions for almost every challenge, even on other platforms listed in the repo.

You make any workaround? What did you do?

I tried searching for specific programming languages that weren’t listed on OTHERS.lst. I searched in different languages to find any solution but nothing appeared.

I need help with

I want to know if it’s okay to add a new code challenges platform and, if it’s a yes, can I add links that aren’t github raw but plain text instead?
