REVIEW:

Contrary to the other user comments, I have to say that Conversation, by its principal design/logic, is the best (Freeware) IRC client, which I ever used on the Mac!
Conversation works quite simple for new users, but at the same time also allows pro users to issue their text based IRC commands, as they are used to.

CONCERNING THE STALLED DEVELOPMENT:

- In 10.4 on my Intel MacBookPro it still "sort of worked". It was already slow due to the Rosetta (Intel -> PPC) Code translation, and sometimes crashed.
- Meanwhile, 2009-09 with OS 10.5 it practically does not work anymore!
- In 2006-03 the author replied to an inquiry email, stating, that he is working on a version 3.
- I have sent him another email now in 2009-09, and hope for a reply!
