I think since it started many months ago it's gone up pretty consistently ... it's grown steadily and when i wrote this post a couple days ago we were up to 6282 cards being rented out. (Aka Open Contracts)
I'm finally posting this and I see that since then it's gone up another 50
However, I don't check every week and the last check i did was over a month ago when it was about 4500 open contracts.
I have a proposal I'm making that can help for OWNERS RENTING out cards.
Here's the rough draft
What happens is i submit something like this and then usually @asgarth tells me if it's doable and then often makes something much better using that seed of an idea and his knowledge of programming.
What would the owners think?
