grrltalk is a general discussion list. This is where people can introduce themselves, talk about their cats, ruminate about their favourite sci-fi/fantasy authors, or even talk about computer stuff. For this list, being "off-topic" is pretty difficult. A lot of people enjoy chatty and social lists, and this is what this list is for.
"Grrl" is for "girl with a growl". Despite the "grrl" in the name, grrltalk is open to people of all genders.
