Currently, I have 2 small children and like Doug Underwood, I just dont have time to play anymore. That said, there are two things that would make progress on ATTAC continue. The first is time and the second is money. If i had time to play (which i dont), i would and i would update the software. The second is money. If it was worth my while to write ATTAC to pay my rent, that would be one thing.
i still respond to email and stuff and in my rare spare time, write some code and scripts.
I would welcome a partner who has more time to write ATTAC with me. If you know of anyone interested, please email me.
