When running mIRC, click on HELP on the top of the screen, and in the dropdown list click on Message Board.
This will take you to the main mIRC forum.
There are also #mIRC channels on most IRC networks, not just DALnet. So, if you can not get your answer on our Channel, there are other places to check.
Also there is a good tutorial on basic scripting located at our website which is www.mirc.org.
