mIRC is a configurable IRC client that has an intuitive user interface, an events handler, and full send-and-receive capabilities for DCC (direct client connection) files (see screen shot). It also has color text, aliases, remote commands, a backgrounds option, and sound. It automatically opens Web sites as they are mentioned in a conversation, ignores DCC Sends that match specified filenames or types, and locks the program to disable various features.
Version 5.82 features a host of bug fixes and improvements over 5.81.
Note: This is a 30-day trial. Registration cost is $20.
