If you haven't been able to attend DrupalCon Paris, or missed the session I led on Views for developers there, you can find its first part on archive.org:

If you are [considering] working on an e-Commerce site, and are coming to the Szeged Drupalcon, you may be interested in several sessions around the theme. In order for your session(s) of choice to stand a chance of being actually part of the conference program, you should vote for the sessions you would like to attend.

Subjet to approval by the conference board, I will be animating/presenting a session about the internals of the e-Commerce suite: see http://szeged2008.drupalcon.org/program/sessions/developing-e-commerce for more details. If this is of interest to you, vote on the session to make sure it will indeed be included in the conference program.
