say, I'm not having any luck finding the "Queue" to see where my email message is up to, where's the queue located at in ACP - VB 3.8.1?

The main ACP page when you log in. You'll see it there.

<removed>

1. Mod file(s) as stated in the Cron-Mail-Queue.txt
2. Backup orig. files. Upload edited to appropriate locations. Upload other file needed.
3. Install xml through ACP
4. Configure number of emails per hour:
ACP> VB Options> Email Options>
Find: Use Mailqueue System.
Change to Yes
Find: Number of Emails to Send Per Batch
Set to 50, 60, 70, etc.
**NOTE** Cron job runs every 10 minutes by default / when isntalled. So if you send 50 per batch, 6 times an hour, that would be 300 per hour.
To view the queue, log into your ACP, scroll down past the Notices, and you'll find:
Mailqueue Quick Stats
To view the cron job:
ACP> Scheduled Tasks> Scheduled Task Manager>
where you will find: "Process Mail Queue for vBulletin 3.7"
You can view the cron job, edit / disable, and or manually run the job by clicking the "Run Now" button.

Other than that, it's pretty straight forward.

Thanks a lot.

Atleast someone provided support to this mod.

I'm unable to see mailqueue quick stats past notices in admincp.

can u help to find?

Not really sure what you're looking for.
Unless there are emails sitting in the queue, waiting to be sent by the cron job, then it should read: "The mail queue is currently empty."

Is there something else you are looking for? And it's entirely possible that there's something I'm not aware of, due to the expansive documentation on this mod. :o

You can see some other very basic information showing that the script ran by going here:
ACP> Statistics and Logs> Scheduled Task Log> select "Process Mail Queue" from the drop down, and it will give you the entries of the cron job running at its scheduled intervals.

You've told that "To view the queue, log into your ACP, scroll down past the Notices, and you'll find: Mailqueue Quick Stats"

I'm unable to find that.

The only way it would not appear is if you havent turned mail queuing on.

I wonder if its posible to modify it to start sending mails at night time ( when the server load are low )

I've enabled mailqueue and it's also showing in logs but not showing any option named mailqueue quick stats in admincp.

Great
