Maybe this will help :P
I noticed that you want to welcome back users when they are in the wb.ini file, and if they are not they will be welcomed with an other msg. But there was not a write ini to get info and welcome users that join the channel for the 2nd, Nth time..
So I edited the code and there you go..
Don't know if this will do the trick, because I am not that kind of an expert on mSL.. So make sure you check the brackets etc.. :P
on *:join:#: {
if ($readini(wb.ini, n, $chan, $nick) == yes) {
if (%flood) { return }
set -u30 %flood on
msg $chan Welcome back to the stream $nick ( $+ $nick($chan,0) in chat)
}
else {
writeini wb.ini, $chan, $nick, yes
if (%flood) { return }
set -u30 %flood on
msg $chan Welcome to the stream $nick I hope you enjoy your stay ( $+ $nick($chan,0) in chat)
}
