OK, here's the following, on http://www.bcgeldrop.nl.
* i have manually added 160 email addresses as 'Public subscribers'
* they receive EACH new post on the blog in EACH category
* every day i notice that people sign off (which is okay) because they receive too many mails on categories that are not on their interest.
Is it possible to give these 160 public subscribers the option to chose which categories they would like to receive news on? My feelings says it's not, because they are no WordPress users with a profile.
I hope my question is clear.
