Guidelines for Forum Use

When creating a new topic:

1) Please make sure you are in the correct forum.

This makes it much more likely that the right people will see your question or comment, so you will get a faster and better answer!  Readers will also be able to find old topics more easily.

2) Please look to see if the topic already exists before creating a new one.

This cuts down on repetitive topics, and makes it easier for readers to find the information they are looking for compiled in a single thread.
