Is it possible to add custom fields to the user profile template? Can custom fields contain text boxes and/or button-type choices? And finally, is it possible to search the users database on the basis of those customized fields? So if we added a field that said:

what kind of garden do you maintain? that had the following choices (and a user could choose more than one): urban, county, container

Would it be possible to search for users who maintain county gardens?

Thanks for your help.
