First, please check the online documentation page to make sure you have the latest documentation. Also check the online FAQ page.
Next, you should search the playerstage-users mailing list archive to see if your questions have already been answered.
Next, you should probably spend a few minutes with Google. This often works well, as it picks up P/S/G conversations from all over the place.
If you still need help, you can send email to the mailing list email@example.com and a user or developer may reply to you. Remember that these mails go to hundreds of people, so please be polite and give as much information as you can in your email.
