I never posted a message of the sort: 
``Here guys put this into the draft: ...''. And I don't
want to post one.

All I've been doing is mathematical analysis of the
algorithm(s). And all I've been looking for is an
unambiguious definition.

Read the sentence again please: indefinite article ``a''.
This means ``any'' CRC algorithm.

No there is no error.

Don't you think I can read this myself?

Then again: indefinite article ``a''.
