Just a couple things to note:
the odds of being able to connect to Random USDALnet (irc.dal.net) are slim to none due to the way they have set it to resolve, use a specifc DALnet server.
Its hard to keep the server list current, as networks add and remove servers on a regular basis. Its always best to go to the website for the network you want to join to be sure you know the current servers. You can add the ones you want in file/options/connect, click on add
Connection Refused prolly means the server is full. Try another on that network or a different server port (many have more than one)
