The forward slash has many
legitimate uses in the English language. The same is true for the
dash and the
hyphen.
What none of them can be used for is a substitute for a period. When you do this, it makes your writing nearly incomprehensible. This is a problem when you are telling us why we need to give you money.
Also: PRINT. Typing would be even better. Do not, under any circumstances, use cursive for anything except your signature.
Thank you.
