How do I attach a document to a person's profile?

To attach a document to a person's profile, upload the document to somewhere on the Internet that stores files for you, this could be Dropbox, your website or a myriad of other places. We use Google Drive extensively. Then create a hyperlink people attribute called something like background check document (people / settings / people attributes). You can set it to be viewable at the level you want. Then copy the link to the document and paste that link into that person's profile field. Using hyperlinks as people attributes really extends the capability of your database, not only for linking to documents, but also things like video testimonies, business websites, Facebook pages, news stories, and anything else the Internet offers.

The Notes section was designed for simpler comments like guest notes, pastoral notes, mentoring notes, etc.. You can customize those by category and access level under people then settings then note types.
