This is the wish site for the Wikidot platform itself whereas I think you have been trying to join the aqwwiki site. Is it that site that you want the how-to for or for using Wikidot sites in general?

In general if you have questions about using Wikidot or you want to look at how-tos etc you should go to the Community site at http://community.wikidot.com where you will get quick and helpful assistance.

I have rated this up - many of my joiners to my sites had big problems to understand what is going on… an when will come an email toc onfirm and can they have all other pages open parallel or/and wich cookies are needed and is javascript really needed ( and what is this ?) …
Most of teh users have no idea ( especially the odler one's) what we are talking about here…
