Its not officially official, but this contains the answers to most basic questions (and a lot of not so basic):
Tavmjong's Manual

How did I leave out that one? It's an essential resource. I've added it to the original post. Thanks

Don't miss out inkscapetutorials.com and planet.inkscape.org

as far as tutroials listings go, i have been trying to collate a list of tutorials here:
http://wiki.inkscape.org/wiki/index.php/TutorialsAndHelp

also, there is a tutorial site "pixel2life" that has a inkscape category, which contains a list of tutorials...
(i submit mine there whenever i get the chance to do a new one...)
http://www.pixel2life.com/tutorials/inkscape/


also, when openclipart is back up, im thinking of collating a list of tutorials there as well, there is new code in ccHost (the engine that powers the openclipartlibrary) that allows an item to be uploaded with a URL as the source, thats when OCAL is back up anyways...

This is not 'Official', but it does help in learning about Inkscape's shortcut keys.

Inkscape Keyboard Layout/Shortcuts v0.48

Anyone know how one can get this file into the "Official Inkscape Resources"?

Hope someone would see this one

Why there`s no installer 48.5 for Windows among other available, on inskcape.org?
One may find links to download this particular edition on some obscure sites, with "possible" third party "offers"?!

The Inkscape website has gone offline (unexpectedly, upstream from inkscape.org). We keep expecting it back any minute, but days keep going by....

Apologies for inconvenience. Please be patient, hopefully all will be back soon.

All, but two weeks of latest uploads in the gallery.
Database error.
More info here.

The website is back online, with downloads, at least with recent versions available. ALL downloads may not be available yet, I'm not sure about that.

Thanks for all these links:) It seems I have a lot of reading to do.
