BTW, to add to the entertainment value of all, the last communication from Tom was that although he was experiencing financial issues, he would pay me back for sure after the 1st of the year. I figured since it is now May, that qualifies as after the first. Anyway, whatever, to save anyone else the potential hassle in case he pops back up under another username or on another web forum, watch out for:

Perhaps it's time to visit your Postmaster, as previously mentioned. Call? Remember, you are dealing at the Post Office level. Their primary mode of communication is written. When you get hired, they send you a letter. At the Post Office, it's all about the hard copy. So you must go there and fill out a few forms. That's it. Don't worry about where he lives or if he moved or anything else. $300 is still a lot of money, and you will see some action. Even criminals will try and avoid the Federal Penitentiary.
I am a retired "Postal Employee" and feel the advice given you above will sort this thing out.
Take the time to visit your local Post Office. The Postmaster is an expert at handling these things. They are in business, (service if you will), not for profit, but to serve you. You will be amazed at the efficiency of the Postal Inspection Service.
What you have described is what computer geeks might call a "fatal error" and easily resolvable. Using the United States Post Office like you said he did, constitutes a serious Federal Crime, and the Inspectors "Always get their man......................."
No need to vent here anymore; just go "postal" on him.
