I hear ya, me too! If you can find an email address, you can send your resume/interest letter that way. Or if you just have a name, sometimes you can puzzle out the email address, just by looking at the way other people in the organization have theirs styled.
If you don't have a name, you can also just mail your resume and cover letter addressed directly to:
Nurse Manager, L&D,
City, State, Zip.
This has worked for me in the past, though not for an L&D job. Sending it priority mail, flat rate envelope, is an attention getter. The $5 isn't cheap so I reserved this for jobs I was REALLY interested in
