I posted a question 2 days ago but there is no answer. Why?
(The website is busy?, The question is not interesting?, or anything else?)
The better thing to do is to go to the thread that hasn't had any response and post a polite statement there, something like "I would still appreciate some help with this question." That will bump the thread up into more recents posts.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
