Is there an easy if-then-else statement I can
use to determine if I am in a specific channel?

/help if then else
/help $me

That works perfect. Was thinking isin vs ison. Thanks!

isin operator means to see something inside a string, so if $me isin $chan will have to tell mirc to check if your nickname is within the channel name.

#chan_holbrook <- this channel name will trigger the isin operator.

I've seen them both used mistakenly in the past.
