I need some tips on how to make TC's fairly quickly. Anyone help!

There are many ways.

You can join and win in official servers (the static ones like Begginer Judo, Begginer Aikido, Blackbelt Judo, quick aikido, etc), win in tournaments and duels, bet, and many other ways.

You can also sell items or textures at the Market, or participate in Events. There are many ways to gain TC. Here is a guide from the FAQ that may help you: http://forum.toribash.com/showthread.php?t=7502

I know but I lost my 3rd Dan account. I'd win in those to easy. I do have texure sets I can sell though. I was thinking more towards how to get more items and sell them higher. I need market tips too.

You can also buy boosters with real money. Also, a good tip for marketing is "buy low, and sell high." But the majority of people in the forums have little or no patience, so they cannot achieve that goal.

You can buy TC with paypal, I think there are some good TC shops, but not sure, maybe there re-stocking,or if you want ti quick you could go to the Shop.

You can do surveys but sometimes they don't work.So just stick to the video surveys those will work fine.You can find them in shop BTW.:3
