I've just rated at five stars the above Wikipedia link and suggest that as many others as possible ought to do so to preserve the entry.
Looking at the deletion message, it seems to me that probably lots of JW's have been alerted by the WT and have been giving it a very low rating. Possibly the WT lawyers have been onto Wikipedia too.
But we can do what we can.
No. The article was submitted for deletion because it fails the criteria for inclusion. Popularity is not the benchmark for inclusion, and giving the article a star rating will not improve its suitability for inclusion. Unless/until the subject is covered in reliable sources (by Wikipedia's standards), it does not belong there.
