DD has again taken the lead in making a mature decision about what we post and don't post here. There is a lot to be said for taking the safe, narrow path route in life (I know that because I knew for YEARS that I'd never live to see 21).
Very simply, there's a lot of neat stuff out there that is either illegal or might be illegal; this is not the place for it.
I overbuild cannon and mortars because I don't want to give any cause for hitting the national news. The same principle goes here - some things you do because it's just prudent.
