So, I am making headway. Thanks to the gentlemen who nudged me onto the right path.
Quick word to Bruno Desthuilliers: while I appreciate that you have greater experience and might find others' endeavours ridiculous, you could be more helpful and respectful in your tone. Do you see a difference between your response and that of Tom Evans, for example? There is a civilised way to disagree. This was not the first time that you and I have had something of a spat regarding your demeanour on this mailing list. The last time, you attacked a total novice to Django with the same air of wanton condescension -and worse, you condescended to Kaste (an experienced Django user) who was trying to come to the aid of said newbie. This is a place where people 'fraternise', and mostly the goal of it all is to enlighten those that need to be enlightened. There is *absolutely* no reason to be uncouth about it. You were also once devoid of comprehension, and you gradually attained it, in no small part thanks to others' patience and advice.
