When I ask a question here, why do I have to wait so long to get an answer? Even the number of users who have seen my questions is small.
I am not new here; I had an account before but I lost the password.
I sympathize with your impatience; and I understand that it’s even more frustrating when you consider how few users we have at this point. But ELL is a small site because it is also a very new site—less than ten weeks old as I write this. With that in mind, let’s compare ELL to other new SE sites (these are the latest numbers posted at SE's stats page:
Note first that ELL has substantially more questions (and questions per day) to be answered than do any of our sisters. And note, too, that we have a much higher proportion of questions to users than our sisters: they have 5 to 7½ questions per 10 users, we have almost 9 per 10. That means we have also a higher proportion of people asking questions to people answering them. And in fact, if you go to the Users page here and look at who does what, you will find that two thirds of the answers have come from just 24 people—half have come from just 13.
And of course those dozen or so principal answerers are scattered around the globe, and work on very different schedules. They tend, too, to ‘specialize’: some of them are most comfortable with questions about idiom, some with questions about formal use, and so forth—I myself prefer questions about syntax and verb forms.
So you may have to wait a while for the two or three people most likely to answer your question to come on line. But I think you can be fairly sure that you will get an answer eventually. The table above shows that 99% percent of our questions are answered, and in fact it’s better than that: the unanswered questions page shows only 3 questions (out of 1088) actually have no answer.
Firstly, ELL is a new Stack Exchange site, still in "beta" mode, so it doesn't have that many users yet.
Secondly, how do you define "wait too much time"? Sometimes a misleading answer may be posted within minutes; you would be well advised to wait until more people have at least seen and commented/voted on any responses. Not every answer is automatically "correct" just because someone posted it.
Thirdly, bear in mind that those people who can answer your questions don't get paid for doing this. If your questions don't appeal to them, why should they answer? Personally I don't find your questions particularly interesting - I have the impression you're just using ELL as a free "proof-reading" service for a work-related technical specification project that would probably be better dealt with by hiring a commercial translator with experience in your line of business.
