PFD's contest for artists and animators

Guess this is a dumb question, but can you only use PFD tubes for the contest?

You can gift them, buy Exclusive Club membership and tubes with them and invest into prepaid projects.

what exactly can u do with credits?

You can send tags you already made if you think they illustrate any of those values, but only as long as you did not enter them in any previous PFD contests.

you can submit as many as you want, the more the better.

can we submit as many as we want or only three?

OH WOW! Great contest! Will have to try..

You can use regular tubes, exclusive tubes and bonus tubes for that.

Can we send tags already made or must to be exclusive and brand new tags for the contest? :)
