Managing Submissions / Timing Question

Just wondered how you handled your TGP / LL submissions?

Do you find if you submit them automatically at a certain time of day you do better with getting listed or not?

Also, have you noticed, if you run a TGP yourself that you are getting more submissions at a certain time of the day?

The reason im asking is that i am considering only having the submit form on Cum Soda open for a couple of hours each day instead of all the time, do you think there would be any problems with doing this or not?

Regards,
