A mutual acquaintance (John Houston) has mentioned that you are looking for an article describing how to use the Steel Beasts ProPE map editor. Is there something in specific you are looking to learn how to use?
I've done a lot of work for SBProPE in terms of beta-testing. I've also had a hand in writing the SB Wiki Scenario Design Guide. I'd be glad to help, if you have a matter that needs resolution.
