Modification in existing opensource news script (cutenews.ru)

i need a modification in cutenews.ru. I want to use it as a private script in order to manipulate the balances/credits/debits of my customers. Some changes in the existing fields are needed and one new automated field and some other minor editings. Take a look at the deliverables. ## Deliverables I am using this script: <[login to view URL]> and i have modified it a little, so you will have to work on my modified version. The requirement is that i do not need it for articles, but to check the balances/credits/debits of my customers. So i need some specific changes in this script: 1) Script has a field named "short story" and one named "full story" (I decide whether they should appear in user side using the script's template system). I would like the "short story" to become "debit", the "full story" to become "credit" and a new field to be created called "balance". 2) The balance field could be hidden from administration, as it will be automatically generated and shown to user side. An example is: on 10/10/2007 i insert a new article: category: Jason Smith (my customer) -the category manipulation already exists, nothing to be changed by you- debit: 100 euros credit: 5 euros general customer balance (automatically generated): 95 euros on 11/11/2007 i insert a new article: category: Jason Smith (my customer) -the category manipulation already exists, nothing to be changed by you- debit: 50 euros credit: 30 euros general customer balance (automatically generated): 115 euros on 12/12/2007 i insert a new article: category: Jason Smith (my customer) -the category manipulation already exists, nothing to be changed by you- debit: 0 euros credit: 100 euros general customer balance (automatically generated): 15 euros 3) All articles are also editable, so balanced have to be updated in articles that are edited. 4) The general customer balance field should appear anywhere i would like in user side. So you could take care about it using the existing cutenews sql template system (for example make a new template tag like {balance} ) I will send you login details in my server account when the bid is closed and coder selected. That's all. I will probably need the coder of this project for other projects in the near future, so keep it in mind. ## Platform php/mysql/apache
