UPDATE: I figured out the subscriptions and how to delete them and/or change them to no email notifications. I just clicked on subscriptions, and then clicked all of them (they are listed on multiple pages, so you have to go to each page and select all of them), went to the bottom of that list that was all checked, and used the drop-down menu to make a selection (you can delete, move, or change notification settings to a specific type of email preference), then hit "Save" I think. It worked!

I'm also learning the BB Code thingy slowly.

It's not so intimidating anymore. Yay.
