I often check the site and see questions that I can answer while I am on the go on my mobile device. But I (obviously) don't have blender on my tablet, so I can't add any screenshots. Usually I forgo answering the question and by the time I have access to a computer I have forgotten about it. Most of the time the question gets answered (which is fine) but sometimes not.
So my question is this, is it acceptable to answer a question without access to blender and post applicable screenshots later? And if so, should I say something like “I will post a screenshot shortly, when I can” in the answer?
