How to delete the unwanted resources?

Dear MHS Webbies,

I wrote an article during January 2011.
It was rejected due to less content. Now I tried many times to update the articles in more than 300 words but it still not accepting and showing 55 words only.

Is this technical error?
or
My account is blocked for resource?
or
Repeated resources delete button is not available.
or
Just a minor error from MHS.

Please resolve this problem and guide further.

NOW I want to delete these resources and write the fresh ones. Please guide.

Regards.
Arvind Kuril
