Question on Mail Art Calls

I have been requested to put up this question:

Mail art - Would you participate in a call for International Mail Art knowing you were only going to receiving documentation. Not a catalogue. AND Would you pay to participate in an International Mail Art Call IF monies were going towards producing a catalogue ...

Why do you trade Artist Trading Cards?

Why do you like trading ATC's? Some people get a rush just from the trade itself. Like bidding at an auction or closing an important sale. For others it's the collection itself. They want ownership of the little masterpieces and to watch their collection grow. Still others, like the exchange and interaction with other artists who share the same passion, the collection is secondary to the discussion that took place during the trade. I myself try to strike a balance. I don't trade as often as other people do, but I can tell you a bit about a each card, and hopefully a bit about each person I trade with. What are your thoughts on this?

Censorship

Part of a post that PatiB put on the Paintnthings website read
" There is a discussion ongoing regarding censorship versus what is appropriate to post on web sites that are open to the general public. There have been some questions of personal sensibilities, questionable images, exploitation of the female figure, and so on ... a very interesting subject paired with mailart and non-censorship issues".

What is your view on censorship versus what is appropriate to post on websites that are open to the general public?
and:
What is your view on censorship in the arts in general?

How long do you spend on each ATC?

How long do you spend (on average) creating each card? Maybe I'm missing something here, but I spend about 3 hourse (give or take depending on the card) on each card. I'm not saying you should, or shouldn't. It's just what I do. I have a hard time getting a lot of cards ahead to trade. Anyone else in the same boat?
