Specific situation: I found an answer to what I was looking for in a reply to a question on stackoverflow.com, took the code and adapted it. But then I found out that two lines of code needed to be inverted to work. Now, I don't have reputation, therefore I cannot reply to an answer and write what I had to do so that others might benefit from it. I can only post a reply to the question but if I do so, the website generously gives the advice to avoid responding to other answers.
This leads me to the general issue - if I want to write a quick fix that made an answer work for me and I have no reputation, the only way I can do that is by responding to the question - a thing that should be avoided. Therefore I cannot do anything (or if I do it, I am not doing it right) and other people that might benefit from it will not until I get some minimal reputation. Let's say I find this peculiar for a helping community.
I already spent too much time to:
- first find out why was the code not working for me;
- then understand why I cannot reply to an answer (btw, this might be nice to have option since you get the feedback for other things for which you lack reputation, i.e. voting answers)
- then I got this reputation thing and I spent time to find out if someone else posted this question not to get a negative vote and loose reputation [I have no idea why since I have no reputation, but this reputation currency got me, so I believe it has a good idea inside]
- Trying to make some sense in this suggestion after the no-reputation 'trauma'
Not to mention that I created the account in the same idea - to vote some better answers that proved more useful for me than others. But as you guessed I could not 'contribute' at all.
This being said, I will close the tab where I could provide an useful reply to an answer and forget about this since now I found my answer.
Maybe this is not so important for you guys, but I don't have the time to build reputations and win medals to give a quick fix to a piece of code and I suggest you allow this with the acceptance of the user who responded (or whatever trick you find acceptable).
