Because we have so many new users recently and start running out of a decent selection of lots for new users, I have today enlarged the empire world by 176 lots, so 2 full rows of lots all around. There are now plenty of new lots in all biome types.
Since the bottom-left corner should still be A1, I had to shift all lots by 2 letters/digits, so if you were K11, you are now M13. You access rights etc should not have changed of course. To my knowledge, all website documentation such as the maps, borders, the settlers questionnaire etc have been changed. If you still find something that is not correct on the website, please tell me.
