Dizzy you can use the grid copy and paste games but it's a bit more complicated than msn does it. It's because you have to put a different name or number in the subject line everytime someone else posts. It can be a hassle if you have lots of members. I experimented with it myself and I don't recommend it.
A lot of members are trying to find a place where they can make websets from scratch but haven't found any yet. Your best bet is to use the webset maker from Chat Central here. I'm giving up making websets because I won't be needing them anymore.
Good luck to all of you
