I have a memory trial subs being handed out on some seemingly random basis at some time in the past. Don't know if that still is going on, though.

I remember that with my old account too.
It was a couple years ago and we got it for a week.

One-week trial subscriptions are randomly given out already.

Oh! I didn't know that. That's pretty cool though. ^^

You can get a week free, I think I got that twice before I got my sub.

As said above...
Perhaps, instead of distributing randomly, they could give an option in the profile or settings to trigger a one week sub. Say once a year.
Advantage: Will happen when the deviant is sure to be in a period they will use dA (no holidays, etc.). Allows to try again to see if new features (like folder CSS) are worth the try.
Disadvantage: It is harder to control the amount of subbed deviants.

82% of statistics in signatures are made up. (This is a recursive signature...)
Spreading them is un-original and sheepish. If you agree, copy this in your... wait, no!
No to signature clichés! You are on an art site, be creative!

There you go. But true, there would be like 100 more times the amount of subscribers.. @_@

Well, the trial won't start until you log in, so technically they will always get at least one use out of it regardless of holidays.
