3-Lib Chats. Each Saturday night (from 5PM to 6PM GMT), Steve Litchfield (yes, the Steve Litchfield who runs 3-Lib) and myself run on-line chats in his Java based chat room. This is a 'free for all' and anyone who's interested and has a Java enabled web browser can come along and join in. It's a real time chat, so messages fly about all over the place to all the people who are there. It's an ideal chance to talk almost person to person with other users and also several of the main shareware authors too, who also make a point of coming along when they can.
And in a similar vein, there are also occasionally chats on a Sunday night (also from 5PM to 6PM GMT) in the same chat room. Although this is still open to everyone, it's mainly aimed at developers from the Psion community, and provides an opportunity for them to chat about developing and related items, exchange code, help each other, etc.
Both chats are (almost always :-) ) very interesting and enjoyable. Make sure you come along if you get chance!
