I was PM'd about how to and To send a recipe from BeerSmith to a friend
To send a BeerSmith recipe right click on the recipe in the brewlog (list of recipes) and select "export as"
the middle option gives several options, select "text"
better, have him get BeerSmith and send him the BeerSmith file format (.bsm file) (same method as above) and he can than manipulate the recipe
Also available are Beer XML file format and web or custom file format.
