While browsing questions on Stack Overflow, I managed to find the answer to well-received unanswered question on the AutoHotkey Forums.
The answer is fairly well written, and includes both a code-block demonstrating the solution, and a complete explanation of how the posted code works.
On one hand, I think reposting and citing the answer would be helpful, as it provides a fairly definitive answer. On the other hand, I'm not sure whether simply citing the answer is enough.
Is it acceptable to repost answers from an external site if I give proper attribution? What would proper attribution look like?
