Do you submit your tgp galleries to Search Engines?
 

After you make a gallery do you submit it to SE's or do you take it down after it makes the TGP rounds ?

no you dont need to the spiders will pick them up from visiting the tgps regularly.

If you want you can link to your galleries from your own site that has PR to ensure they get spidered. But if you use the same template then they will ignore most of them so they need to be all different even if the change is minor etc.

So you defenitely advise me to leave them up?

I will make them different. Thanks.
