A comment sort of answered my question, how do I marked it answered

Question

So I made this question earlier

pdflatex stuck compiling, gives no error

and a commenter pointed me towards what could be wrong, I changed my document accordingly and now everything works. I want to mark the question answered.

Should I wait for the commenter to post an answer or should I answer the question and add the changes I made to the document ??

Related/duplicate: What if a comment answers a question?

Quite often it happens that the problem is a typo or alike and we consider it off-topic.

However, in this case I would ask Ian Thompson to provide an answer, since the question carries information that can be useful to others :)
