Lightfin once whispered in the wind:
At the startup screen, across the top under the picture you'll see two lines; the first includes "Discussion Board" and "Photo Gallery." Under those are three subheadings each. The middle section under "Photo Gallery" is F.A.Q (Frequently Asked Questions. Click on F.A.Q.) and you will find several board use related questions and answers that may help you find what you need.
I find this to be a great board, and believe you will find persevering worth the effort.
Unfortunately, a FAQ is a feeble substitute for real documentation
For example, the question that started this thread is not addressed in the FAQ. More generally, what do ALL the icons mean? How do I find new replies to articles that I read previously? How do I mark a particular thread as uninteresting even if it gets new posts? What would I ask about, if only I knew the feature existed?
I agree that this is a fine board, which reflects the people who post here. I just observe that the user documentation
is poor, a feature that it has in common with nearly every web-based forum I've ever seen.
