Hi, we want to create a system where our users can manage their subscription options and choose which types of information they would like to be emailed to them. Something like this: http://www.beehive.govt.nz/lists/index.cfm how would you do it? We currently have a documents library with about 10 different types of documents written by 9 different authors categorised in about 60 topic categories. http://www.greens.org.nz/docs/ Ideally whenever a new document was added and categorised, it would be emailed to all the users that have signed up for that category. We currently have a database of 10000's of people who have expressed an interest in certain topics http://www.greens.org.nz/office/interest_areas_form.htm but this only allows them to express an overall yes/no for emails. There is no way that they can choose different options for each one, say * all documents on Drug Law Reform as soon as they are published * a weekly digest of all Security and Intelligence documents * only send me PRs for Tertiary Education, not other types of document * register my interest in Transport, Climate Change and Trade but don't send me anything on these. etc etc A document could be categorised in multiple topic categories, so there would need to be some sort of checking so that if a user had signed up to receive docs from multiple categories that they didn't receive the same doc twice. We would like the users to be able to check what information they have given us and make changes to it. The database is currently in Access. The documents library is currently written in ASP. So how would you go about this? cheers Dr Stuart Young, +64 (0)9-815 4321 Ex 8656 <syoung at unitec.ac.nz> Lecturer, School of Computing and Information Technology, UNITEC Institute of Technology, Auckland, New Zealand "Have I lost faith in Microsoft?
