Certified Mail

<p>Hi all,</p>

<p>Did any of you guys have any problems with sending USPS Certified Mail?</p>

<p>Does anybody know? I sent a supplement via certified mail, but it seems like they’ll be closed from now until Monday. What happens if nobody signs for it?</p>

<p>Should I just send another copy regular mail to make sure?</p>

<p>Thanks.</p>
