Hello dear support,
There is an issue in used language strings:
When Guest user clicks on Write review he see You are posting review as Guest (Login Now):

But if user wants to post comment or replay to it he gets the same:
You are posting review as Guest (Login Now):

But it should be You are posting review as Guest (Login Now):

Also the button when user posts comment should say Add Comment or Post comment

I would like to see this corrected in next version od JlexReview

Thank you!
