On most SE sites, when someone suggests an answer to your question you can check it fairly quickly. Certainly with a lot of the IT related questions you can typically verify if something works in minutes to hours, and so you can usually decide an answer is correct and accept it quite quickly.
Here, some questions can be accepted quite quickly, but other classes of question you can't verify that the answer is correct until you're actually there. Depending on how organised you were about asking the question, that could potentially mean it's many weeks until you're in a position to accept. (I've got 3 questions open for example, which I won't be ready to accept answers on or update to indicate problems with them for another week)
My hunch is that this isn't an issue, but as it's different to other SE sites it may need to be in the FAQ to explain this to people coming in from elsewhere in the network. What do we think, is waiting to accept this kind of question until you try the suggestion correct, and if so is a FAQ entry about it the right way to explain this potential difference with the site?
