You do need to be % status or higher in the channel you type +/-IMDB in, to turn on/off.

That part I understood, and I was % in the channel I was trying to use it in.

@s3ff3r To test the script type /eimdb movienamehere (From the client that is running the script)
If this works then the script is working fine.
Something to consider::
This script is made for a bot and requires a second client to trigger it.
You will not see the results of a movie search from the client running the script unless you are using the /eimdb command.
The output to the screen is suppressed to conserve the bots resources.
