low on my list would be a phone call or email that I cannot prove...
In lieu of no updates in the filings, no correct phone numbers or correct addresses in the filings and overdue filings, one could assume that a few questions need to be answered by picking up the phone. Now that person could assume they won't get all the answers they'd like, for legal reasons, but you may be able to gather some insight, tidbits, direction. One never knows what can happen when they decide to work for themself.
