Hey zapt0, maybe it would be better to add archive parameter to the class header, use my parse_index method and modify my cleanup:

class AdvancedUserRecipe1299694372(BasicNewsRecipe):
    title                             = u'Instapaper'
    archive                         = False

...

def parse_index(self):
        totalfeeds = []
        lfeeds = self.get_feeds()
        for feedobj in lfeeds:
            feedtitle, feedurl = feedobj
            self.report_progress(0, _('Fetching feed')+' %s...'%(feedtitle if feedtitle else feedurl))
            articles = []
            soup = self.index_to_soup(feedurl)
            self.myFormKey = soup.find('input', attrs={'name': 'form_key'})['value']
            for item in soup.findAll('div', attrs={'class':'cornerControls'}):
                description = self.tag_to_string(item.div)
                atag = item.a
                if atag and atag.has_key('href'):
                    url         = atag['href']
                    articles.append({
                                     'url'        :url
                                    })
            totalfeeds.append((feedtitle, articles))
        return totalfeeds

    def cleanup(self):
        if self.archive:
            params = urllib.urlencode(dict(form_key=self.myFormKey, submit="Archive All"))
            self.browser.open("http://www.instapaper.com/bulk-archive", params)

Users wanting auto-archive then change just one line:

archive = True
