We have installed gravity forms and the user registration add on.
I would like to add a keyword/tag field for each user to add tags to their profile (like a post, but for a user). Our aim is to send notifications to users when posts are created with tags that match their user meta tags. So first the user needs to specify what they are interested in.
Now I can add a plain input or text field to the custom registration now which works, but I would like to add the functionality similar to that in the tag widget / wordcloud widget found in wp-admin.
Can you please give me instructions as to how I'd call the same functions that create post tags and post cloud (with the autocomplete etc) in wp-admin - but 1/ to add this to the user registration page and 2/ save the tags as user meta.
