What issues exactly did you have with contributing? I found it very easy to contribute to alpine, I wrote an APKBUILD, created a pull request, someone reviewed my PR and pointed out an issue, I fixed it and my PR was merged. I can't think of a way that could be made any easier.
I looked at multiple messages on that website and the pattern seems to be triple letters are for single letters and abbreviations. My theory is because if you get a letter wrong in a word and "possible" becomes "possifle" then it is still intelligible, but if "u five one four" means u-boat 514 and you get the U wrong, then it could end up as A514 and mean something airplane 514, so to be safe the letter u gets transmitted thrice.
1. Create a recursive symlink to itself: `ln -s test test`
2. open superfile and navigate to it.
3. Observe crash
