You don't have to post to a thread just to get updates. Just hit notify! Please!
When everyone posts for updates only, it makes a thread long and (on some systems) unmanageable!
Please hit "notify" instead!
If you've hit notify, to find them, just go to your profile, account settings, then under the modify profile icon will be "notifications". There, it will list all of the threads you want to be notified on.
If someone knows an easier way to get there (without getting e-mails), please let me know!
