I am a long time lurker on stackoverflow. There was a time I was stuck on an obscure error for so long but finally light shone when I found an answer to that problem on stackoverflow.

Overjoyed, all I wanted is to leave an upvote for the answer; before I realised that you need a +15 reputation before you can do (I know I am late in this game)

So I worked my way to that 15 and it was a tedious one. Stackoverlords deleting my answer, voting no to my edit and reverting another over petty reasons

I fought back by flagging my deleted answer with my reasons and alas the community backed me up by upvoting my answer (which was revived),the original answer poster approved my edit and @me a thank you comment. I was elated

And it is today, I got my +15. That I could finally pay back and upvote the answer from my benefactor
