Here are some other punctuation marks you can use to connect independent clauses, along with the conditions:
* Comma + coordinating conjunction: Use a comma followed by a coordinating conjunction (for, and, nor, but, or, yet, so) to connect independent clauses.
* Colon: Use a colon if the second clause explains or expands on the first clause.
* Dash: Use a dash to connect clauses that have a close relationship or are particularly dramatic.
Let me know if you'd like examples of any of these!
