I'm concerned that good-faith edits (hundreds of them) by one user, relating to WikiLovesMonumnts in the UK, have i) used date templates where they're not appropriate and ii) lost lots of existing wikilinks, including disambiguation, which other editors are now being asked to replace. Please see http://en.wikipedia.org/wiki/Wikipedia_talk:UK_Wikipedians%27_notice_board#L...
for examples and discussion.
We may need a mass revert (after which the edits can be reinstated in better shape); or a bot to do cleanup.
