I am also trying to enter the reason for the ban, so that both admin and user can see it. Did you ever figure out how to implement this on your site? Thanks
Yes, after a bit of tinkering I got it down.
I am using the string
getstr bye "msg x ban %c %s 24 400" "Ban with reason:"
which will then have a result reason as 'bye' but will provide me with a user input window where I can enter custom reasons.
