...such wonderful benefits.

[Tan Elaine]

Those who are attending Propagation Discussion are accumulating such wonderful benefits.

Is 'such' correctly used in the sentence? if not, what is a suitable word to replace it?

Thanks.

Yes, it is. However, I would use "experience" instead of "benefits", and I don't know what "propagation discussion" is supposed to mean.
