Hi all, I've annoyed you guys enough with pointers, objects and clases :P I'm sorry :)
This bugs me though as to why this program crashes at the 4th call to
addNick(nick: String);
Here is the gdb results, and attached is the source code if anyone is
willing to have a look.
thank you very much :)
James
