Japanese is such a highly context-dependent language that questions about the meanings of single sentences out of context are very difficult to answer, not just because the answerer has to do a lot of guesswork, but also because guesswork-based answers aren't going to be that useful to the asker.
I'm new to this site, so I'm not sure how things work around these parts, but on other sites there are "stickies" or "wikis" or rules which explain how questions should be asked.
It seems like it would make this board a lot more useful (for askers) if there were a list of suggestions, including to put as much context as possible, etc.
