this is what mine is showing (pm_newpm template)
Code:
<if condition="$show['trackpm']"><div><label for="cb_receipt"><input type="checkbox" name="receipt" value="1" id="cb_receipt" $checked[receipt] />$vbphrase[request_receipt_for_message]</label></div></if>
my other options (i.e. save copy to sent folder, show signature,) that are marked/checked by default have the same 'value='1' and there is indeed a check in the box beside those options but NOT for the return receipt... would it have a different value number to show?
oh I suppose I should add that only moderators on my board can send return receipts, I had to take it away from the regulars because they NEVER cleared their receipts out... *grumbles* much like they don't clear out their pm's they've sent and received....
