I haven't found a working plugin for cookie-based visitor customization so I'm wondering how to figure this out with some manual work.
I'm running aggregator site with FeedWordPress. Let's say I have a visitor who doesn't want see any category X related news. He fills simple form where he determines those categories. I guess this process can be done via email or form-plugin so...
I need to manually create a customized site to this visitor WITHOUT those categories content appearing (no need to touch menu links, it's ok). After that visitor could always access to this customized "site" either by subdomain or http://mysite.com/user-defined-url. I would like to do this without multiple WP-installations or complicate setups.
Currently I'm using PEFC plugin to hide some categories from my current frontpage. Thank you.
