Note that a year ago, there were around 40 transclusions of this template. Now there are 300 and this is causing problems much more frequently.

Whether new users were encouraged to make small edits rather than create articles is irrelevant - If NPP is involved then they HAVE CREATED AN ARTICLE. At this point, (if they have not received prior welcome messages - per the original description of the request), the reviewer should provide welcome message pertinent to an editor who came here to create an article.

Per NPP analysis.

The help page is now at Help:Unreviewed new page

Yes, that looks fine. If you can format the numbers so the text is more aligned that would be good.

The discussion has now been listed at Village Pump (Proposals) for 12 days which has brought a couple of more opinions. The are many who feel that there is clear consensus between the original RFC and the recent NPP discussion to extend until reviewed. There are still some who think this is a major change and needs more discussion. However, I see no one that is objecting to an extension of the time period. Can we get the extension to 365 implemented NOW at least as an interim step. This would address the immediate problem and leave more time to debate the indefinite issue and whether it has consensus.

The discussion at https://en.wikipedia.org/wiki/Wikipedia_talk:New_pages_patrol/Reviewers#Proposal:_increase_unreviewed_new_page_search_engine_NOINDEX_duration has concluded with explicit consensus that the original RFC be implement - NOINDEX duration should be indefinite, that is the article should remain NOINDEXED until it is reviewed. Please proceed with the change.

The request is not to change wgPageTriageMaxAge from 90 to 365 days, but to have no limit so that articles must be reviewed before they are indexed per the RFC.
