Thusly Derek Benson Spake Unto All:

I haven't tried any other stand-alone newsreaders. I've used Free
Agent since the early or mid 90s, exactly because I'm familiar with
it. I have no interest anymore in trying new computer programs all the
time

It's still the best.

The one thing I'm missing is more options for killfiling, e.g. the
ability to killfile based on text in the body of messages and all
fields in the header.
