I don't know how long it's been since other reviewers have used this (or why they're writing reviews for a new release based their experience from several versions ago), but I've been using Chax for probably a year and I've never had a problem with it. Nice feature set with lots of control over which features you actually want enabled. Easy to install and use. Easy to remove if you don't like it. If you're a fan of iChat over other IM clients, this is a must have if only for tabbed conversations and automatic message acceptance.
