Hi,
We are not yet completly ready (almost all is done, we need more testing), but Ithink that when we will merge the jQuery branch we should use
jQuery.noConflict();
and keep using jQuery( instead of the $( shortcut. Until we all agree about notdoing so.
Because some of us are certainly using Dojo or/and Prototype in their customprojects based on trunk and it would be a nightmare otherwise.
