The first time you start mIRC you have to fill in a bit of info

A channel is like a room. There are many channels on an IRC network You can get a list by clicking on the list channels button on the toolbar. Channels always start with a #
There are a number of ways to join a channel. If you listed the channels then double click on one in the list. If you know a channel you want to join, just type /join [channel] eg /join #chatz
The + means that the person has a voice. If the channel was 'Moderated' then only the @'s and +'s could talk. Not many people moderate channels. It tends to draw people away. The + sign is near enough redundant.
The @ sign before a name means that the person has Op Status. An op can kick, ban, voice, and op other users in the channel. Ops will only ban as a last resort, if people constantly break channel rules, or cause a nusance to other users. In #chatz we have our rules set out on the web page, and soon on the 'BOT' in the channel.
This question is asked a lot, in all channels on all networks. Most ops will immediately kick the person asking. Asking for Ops is a big nono. You can only get Ops if you are a regular visitore to the channel and are trusted by the channel ops and/or owner. It took me well over 2 years to gain ops in one channel.
I personally dont see a problem with everyone haveing a voice. Its not used in any way in #chatz. Other channels do use voice as a kind of heirachy. Its basically up to the operators online at the time.
Most channels have rules. If you want to know what they are, then ask in the channel. On #chatz we have rules, you can view our rules here or when you join the channel, the service (ro)Bot will inform you of them.
