Articles mod for modx: exists or not?

Hi everybody. i have searching for some modules which can do something like this: http://articles.slicehost.com/
Articles modules with a comment option.
If it exists pleaase let me know.

Thank you.

I’m not sure what you linked to... what exactly are you trying to do?

I think i found what i wanted. Jot mod does comments.
I want something that allows people to register (modx does it), write articles (modx does it too) and ability for registered uses to leave comments and contact web site administrator through contact form.

Thanks.
