I recently searched for a problem on SO, and found an old question (with an accepted answer) that resolved my issue. However, the answer is slightly outdated so that I had to do a small workaround. The workaround may have been as little as finding an updated link.
I feel I should mention this workaround, even though the question is old and already accepted.
However, I already posted two answers along those lines and they were deleted instead of being converted to comments. (I don't have enough rep to comment.)
What is the problem?
Are answers on Stack Overflow meant only for the OP, and not for anyone has the same issue as the OP later?
Or should I avoid mentioning the updates to an answer because I don't have enough reputation to comment?
