I recently started a new non-profit organisation and I'm now at the stage of putting together a tagline, but I'm not sure about the correct punctuation to use. I was wondering if it would be correct to write the tagline with a full stop separating the two phrases, rather than to use a comma. The reason I used the full stop is to use the phrases as punch lines and I think the two phrases are conveying two separate messages even though interlinked.
Here is the tagline: Inspiring change. Taking action
Use the full stop. The comma feels very wrong. They are fragments, not full sentences, so it becomes a matter of style. There is no "correct grammar" to govern tag lines when they are made up of fragments.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
