Hello and welcome to the forums
You're just in time for our Annual Contest, so feel free to post something - you never know.
If you like Apophysis, have you tried JWildfire? It's a flamefractal generator too, but is still in development and I hear Apophysis development has slowed.
I'm sure you can learn much here if you ask questions! There are forums for general discussion and many for specific software, so look around, try thr search feature, and post! That's the best way we have to learn here...
Enjoy the site, and I look forward to seeing your work.
