I hope nobody minds me jumping in but as a blind user a couple of folks have asked me if I can provide any pointers regarding using the forum with accessibility software.
I use JAWS with the NS forum and I initially found it quite hard to navigate until I figured out a working flow.
The most useful keyboard shortcut keys to get around the forum are those that handle lists, which in JAWS is the letter L.
By hitting L it will take you to each Division list which hold the forums. This isn't particularly helpful on the main page which lists all of the forums, but it will get you to where you need to be. It's actually best to just struggle through learning all of the different forum subjects so you can just go to your favorites by searching for them.
So in JAWS (and probably Magic, the freedom scientific magnifier), hit l and then arrow down once to hear the first item in each list. The forums typically use definition lists, so you can ignore any list that isn't described as a definition list.
The most confusing thing for the totally blind user is the gameplay forum, which also has a gameplay subforum. It can get you stuck in a loop where you click on the main forum link, when you meant to click on the sub forum (which has all the actual posts).
Once inside a forum, the list keyboard shortcut can really come into it's own. By hitting it until you hear the list with 25 items, you know then that each time you hit the list keyboard key, you will hear a new thread subject. Then you can just click and you'll be in the thread.
So,, here's a working example in JAWS:
Go to the main forum page at
http://forum.nationstates.net/Hit the l key until you hear the first definition list with one item.
Arrow down once and you will hear Diplomacy.
This is a group of forums relating to nation states diplomacy.
Hit l again and you will hear a list of 5 items. These are the sub forums
Each forum is contained in a definition list, so hit L once more and then arrow down to read the forum name.
Arrow down once more and it will describe the forum contents.
Arrow up to the forum link and click on it.
This should open the Factbooks and National Information forum.
Hit l until you hear list of 25 items. This is the list of threads shown on the page.
Each thread is contained in it's own definition list, so hit l once more and the first thread list is selected. Arrow down to read it's subject and keep arrowing down to read the rest of the information about the thread.
Open the thread to read it by clicking on it's link.
Inside a thread the most useful key is the heading keystroke. In jaws that's the h key. Hit it once and the heading level 2 is the forum title. Hit it again and the first post in the thread is selected. Each post in the thread has a heading level 3 and you can use it to rapidly skip down the posts, using the arrow keys to read the ones that you are interested in.
To post a reply, I just search for the Post a Reply link and then click it. Be sure and read the entire thread before posting a reply.
Be sure your reply is pertinent to the thread you are posting in. I know that's obvious but I'm covering my rear end.
Once you've made a few posts you'll probably find the "View my posts" feature incredibly useful. I use the JAWS link dialog to go to it quickly, but if you aren't using JAWS you might want to bookmark the View My Posts link after you locate it. It's the fastest way to watch the threads you've participated in.
I think that's about the best I can do for a quick primer on the forum here. You are welcome to contact me with specific questions via TG if you like.
To the admin / mods, if I shouldn't have responded here, please don't hurt me. :)
