I am running a blog aggregator and I want to implement social tagging to my posts.
The idea is that the tagging system will be open and free, so any registered user could add and/or remove a tag to a post or page while viewing the homepage or the categories page, for example.
I didn´t find any plugin that would allow me to accomplish such a thing (not even close), so I gently ask you:
1. Does WordPress allow a registered user to change other´s tags without changing anything else in the post, like author?
If you could give me any directions so I can start planning a plugin, it´ll be very very appreciated.
I´ve already adapted some plugins to my own needs, and have been wrote others simple ones. I understand a bit of plugin design and coding, but I think this is a bit more complex than what I´ve done so far.
Thanks for your help, anger to hear your opinions even about the validity of such idea.
