David,
Is using the service to insure it will be filed vs. me 'Joe Blow' maybe getting it rejected? I guess just put everything in a packet addressed to the court and hand it to the server? I assume court will send me copies with case file number stamped or similar, a week or so later? How do I 'instantly' prove the R4C is filed when I send response to IRS? I want to be prompt and file before or overnight by 19th of next week. Or maybe it's not that critical, the timing?
