Hello Brad,
Thanks for submitting a question about transferring blocks. The easiest way to accomplish transferring a block is to copy the code (the actually HTML “text” content of the block) and paste it into a different installation where it can be saved a new block in the new location.
You may have noticed that the BoldGrid editor has both a Visual and Text mode. Make sure to use the Text mode to make sure all of the content is selected for copying.
Best,
Christopher M.
