Nix has been helping write the documentation, and I've helped make the Page node markup and putting it all together.
Today on XenFans.com we've started with the first batch and made it public.
You can view it here: http://xenfans.com/pages/how-to-begin/
It's a resource for everybody, but our work. We will of course update it as we get feedback, correct what is perhaps wrong (things changed during alpha->beta->final stage) and we will extend on it with video @ vimeo walkthroughs that are good quality, short and simple.
Linking to the content from your site is obviously appreciated, you might think it benefits your members, help your staff, or yourself, to learn more about XenForo.
Users are of course also welcome to write up something and submit it to us, we have no problem giving you full credits.
Videos if we embed them are free to be remotely embedded.
Text and images however is our work, we rather you consider fair-use than blatantly copy/paste everything. If you do desire to link to it all, please contact us on firstname.lastname@example.org for written permission. Those who ask get a lot further!
The user-guide is finished for 25% which is the part: how to begin.
Tomorrow we will make another 25% public, which will be: all about posting.
By the end of the weekend we will have hopefully finished the whole user-guide section, covering 'your account preferences' section and the 'social' section.
I think it's worth a mention. As we worked hard on it, and we hope it is a useful resource to you and your members.
Future user-guides are hopefully crowd sources, and we populate those as we run into those questions. So don't be shy to ask for anything. We will do our best to make easy to understand documentation for newcomers to the board. Which can be a resource for your staff.
