A few comments have been made about the Polanoid "Forum", how can I access it?

Just bought a 600SE whch is a beautiful beast. Will it improve my photography? Time will tell!

I'm having problems loading a Polaroid 340 with 690 film, I keep getting an oblong track across part of each frame, which I guess is the leader for the next frame. I have obviously loaded it badly but can't see how I can correct it. I have five frames left on this current pack, which will be completely waisted if I use them. Can anybody help?
Thanks!
