Ralph Versteegen is an OHR developer (and Wiki sysop), but not any kind of front for an adorable hamster. I go by the handle TMC on the forums.
I've been using the OHRRPGCE since early 2002, and have been part of the community since roughly the same time. I've been helping to develop it since Quaternion in early 2005, and before that, I wrote a couple utilities like the HS Importer.
I like to focus on low level details like backends and porting the engine, and on the script compiler and interpreter. But mostly I stick around because I love helping people to enjoy their creative hobby by expanding the capabilities of the engine or fixing bugs.
