hi currently after receiving some advice installed spchat (www.spchat.org)

trouble is i am using 7.4 nuke, but cant get the chat block to work showing who is in chat room ... i have made sure the blocks script is in the blocks directory, but it doesnt show up in admin

anyone help us out with this as its a cracking chatroom and even better if the block could be made to work for 7.4
