Your questions depend on alot of factors. While there may appear to be many people in the chat room, the chatters are from different parts of the world and may not be able to answer your question at the time you ask it. Some people might not be next to the computer when you ask your question, or some may not know the answer so they do not respond, and some problems are complicated and can't be addressed in the chat. I answer questions when I have the time, and if I know (or can find) the answer. Some users enter, ask the question and leave less than a minute later (not even enough time for a toilet break).
Alot of people come and go through the chat, some get there problems adressed, some do not, but we do try to get them resolved.
Ask your question, wait around for a while (15 to 20 mins) to see if anybody responds, if its busy, wait a little longer, then come back a few hours later and ask again to see if someone who is able to answer your question is next to the computer.
Try to introduce yourself first, a simple Hi
or better yet: is anybody around to help with a networking issue?
can identify your problem to knowledgable helpers and save you from alot of typing a detailed question if nobody is around.
