re: procmail configurations

I want to filter out all e-mails with subject: [gamedancers] so on.....
and transfer it to a folder. is this syntax of mine correct?

the start of the subject line is always "[gamedancers]" then what follows
always changes depeding on the topic...

:0 
* ^Subject:.*[gamedancers].*
/home/ian/mail/gamedancers/

it doesn't seem to work.....? 

Thanks so much!
