I'm currently using GAIM. However, I see that AOL now has AIM 1.5 for
Linux. Has anyone tried this? I'm wondering if it might be a better choice.

Also, when I signed up for my screen name I got an error message:

aim is not a registered protocol

Is anyone familiar with this? (I'm using Mozilla Debian Package 1.3-4).
I had already received my screen name so it didn't matter (it was just
on clicking a Continue button).

Thanks,
Ray
