Yeah, I know. It's a stupid question. But I really need an answer. The sad thing is, though, is that as little as two years ago I knew very well how to do it.

In editor, press T and choose export or import. If you use export then the board you are currently editing will be exported, if you use import it will place the imported board in the current board's place.

Oh, now I remember. Thank you!
