If a party timely sends a motion for new trial directly to the presiding judge in an email, then that motion is properly filed and will toll the time available to file a notice of appeal so long as: (1) the presiding judge allows the motion to be filed with that judge; and, (2) the presiding judge accepts the motion within the required time-period.
