It's usually best to try and connect to one geographically close, even though that may not be the best. You can always ask when you get on IRC . Here's a list of servers available for connection:
Table: Open IRC servers
This is, by no means, a comprehensive list, but merely a start. Connect to the closest of these servers and join the channel #Twilight_Zone or, if you are in Europe, #EU-Opers . When you get there, immediately ask what you want. Don't say ``I have a question'' because then everyone will ignore you until you say it a few times, and then they'll jump down your throat and rip your lungs out. No-one knows if he can answer your question until you ask it.
