You cannot omit a relative pronoun from a relative clause if it is the subject of the clause. In your example with the -ing form (which is a participle) you have shortened (reduced) the relative clause to a phrase.

Please don't post the same question in two different forums, goldfish. It wastes the time of people who answer it in one forum only to discover that it has already beeen satisfactorily answered in another.

If you are not satisfied with the answer from one forum, please follow it up in that forum first. If you are still not satisfied, then try another forum, but say what sort of amswers you have already received.
