Well I'm new to this forum, but not new to forums in general. Make sure to read the "stickys" on each sub-forum, which will be the bolded topic at the top of the page. These usually provide helpful information.
The cool part about forums is you don't always have to just post... it's generally more helpful (for me at least) to just read other posts, and then respond if something someone says intrigues thought.
Hello and welcomeeeee!!! I'm new too, and I'm also finding it very confusing, haha! Luckily it seems that you posted in the right place, and I commented in the right place, so we're each doing something right!
