I know OrangeXP has been quiet lately, but I did very recently, (within the past 3 days) get a PM from him telling me he is still working on it. However like most of us he has RL duties that only afford him at max a couple of hours to code a day.
I'm sure not every day he rushes home to code it either.
An alternative i've found (though insanely slow and not rendered as well) is cartographer which i guess i will stomach using until this wonderful program is once again ticking.
I say, open source this puppy. My SMP Server crew depends on this mapper, and we're SOL for now. I understand the realities of life get in the way a lot of times, which is why should all work together!
