It was hard to understand what you meant!
you have used "its" instead of "is"
and "developed" instead of developer
so the message should be,
This component is excellent. I can communicate with my user when they are online. The developer of this is working hard to fix any bug. The support is excellent and developer of this extension is doing it for free. Good work
Thanks for the Review. On the downloads page I suggest enabling the module to your templates absolute module position because some templates may give you the result you experienced. I have a guide on our site on how you can add an absolute module positon to your template. Try it.
