I've just finished updating the Useful Links page with all I have been able to glean in a trawl through SFN. If you haven't got the direct link go to Social on the menu bar and it's the bottom item on the list.
It's not perfect -- maybe the headers should be in alphabetical order (?) or grouped by theme (?) -- but I hope you'll find it useful. Any suggestions welcome, particularly for additions to the list; you can leave a comment on the page or send me a message.
As far as I can I've checked the various links to web sites to make sure that they're accurate and still working but I have to admit I haven't called the English-language help lines to check they are right. If something doesn't work or has changed, let me know.
