The thread’s title should hava a period at the end.
An interesting tid-bit I have noticed through the years is that a century ago, all signage would end with a period at the end. For instance, you wouldn’t see a sign that said
Walgreens
but one that said
Walgreens.
Another archaic convention was to hyphenate compound words much more than we do now. “To-day;” “tid-bit.” I lost a spelling bee over it.
