Hi, I need some help with understanding this forum.

I started a thread in general coarse fishing chat, and I've had a couple of replies to it but when I reply to the people who have commented my replies don't seem to be working I've tried to reply directly to each person but that isn't showing up?? I have also tried to comment at the very bottom of my thread with a new question but that doesn't work either?!
I've tried to send a private message to who runs the forum but that hasn't worked either!
Has anyone else experienced this or is it just me being a bit of a div?
