After looking through that snipit of code there are a few things that you need for it to work.
It calls an alias “timeout” but it isn’t defined… You’ll need to write it. It’s simple enough and should look like:
alias timeout {
msg $1 /timeout $2
}
also it uses a hash table called “permit” to see if a user is permitted to post a link so you’ll need to create one before using that script.
