A little help from your friends
One of the great things about being a member of a writing community like the HTTS boot camp forum, is the opportunity to pick the brains of the people you’re in community with.
Need to know a few choice curses in Spanish? Or German? Or Russian? There’s a pretty good chance that someone can help… or at least point you at the right kind of resource.
Doing research on ranks in the military? Or the Police? Or among the personnel on a space frigate? Somebody probably knows all about that.
Trying to understand the science of hyperspace? Or what it would be like to live in a low, or high, gravity environment? Ask! You never know who might have fantastic information for you!
