I have written my own Jommla component for displaying particular information (for example car info: engine power, year and etc.).

Now I want to add a comments to my component.

Implementing comments by my own is too hard and it's not very safe.

Maybe someone had and experience integrating some existing joomla component for an own component?

Update:

Maybe I can copy-paste code of some existing joomla comments component in my own component? Does somebody tried to do this?
