Import

I'll begin an import from en.Wikipedia shortly Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:50, 1 March 2017 (UTC)

I've Hit a number of constraint violations, including 6-0185 and 3-0980. It seems leading zeros, after the dash, are acceptable. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:08, 1 March 2017 (UTC)

No, the source does not have leasing zeroes. Lymantria (talk) 16:26, 1 March 2017 (UTC)

Well, a source clearly does. In fact, a Google search for "6-0185" lighthouse finds more than one. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 23:31, 1 March 2017 (UTC)

Now done; just over 400 found. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 23:31, 1 March 2017 (UTC)
