Stoney, you've got the right mentality... I like that. I only ask for some experience because, despite the "whole team of map makers" that Tracer mentions, we are only a handful of dedicated builders, less than half a dozen... so we're all pretty busy, and don't have time to take anyone under our wings as such.
The TE community is small to begin with. The portion of the TE community that has built SEA- or MA- ready terrains is even smaller. A lot of guys build for H2H, but unfortunately those terrains don't give you much experience building for an HTC server, something that Skuzzy will approve. Also, building for H2H can also instill many bad habits. So it's critical for me to bring someone on who can demonstrate really learning how to use the TE properly.
If you're interest is truly in building something for us, then download the software and start building. Take baby steps through the learning process, don't jump ahead to the cool stuff. Build a simple yet thorough SEA-quality map to learn the process... we'll be glad to help you all you need. But there is no other way to learn than by doing it. Be patient... much of it doesn't make immediate sense, but after a while it will all start to click.
