It's had a rapid decline over the past few months. A year or two ago there was usually 10 to 12 people in there after 22:00 UK time - a good mix of UK based prooners and some early rising antips who would join in the fun.
Being a regular myself, I'm a bit unsure why it has gone downhill. There was a rumour that Danny was not going to renew the Digichat subscription (yes, he had to pay for it!) and that it would one day just not be there. Many of us moved over to MSN so we could remain in touch - there are often 'rooms' with a similar number of bods in there most evenings.
Any old 'chatters' want to add me to their MSN list, I'll invite you in next time some of us are having a natter.
