I sometimes post on 28 days but found that they have a bad image in Scotland, I posted a report on a fireclay mine in Scotland and was immediately contacted by some horrified Scottish mine explorers who were concerned about the mine getting too much publicity, (the mine was in an exceptional state of preservation). I pulled the report as I could see the dangers of such a place becoming too well known but its easy to overlook these sort of concerns, until they are pointed out by someone.
