I know in the town app it says between 100x100 and 200x200, is that the length and with has to be between 100-200 or the area has to be between 40,000 blocks and 10,000. I was just curious because there are towns a bit too close to mine so I can't fit a full 200x200 in-between, I wanted to fit a 100x400 town. Has this been talked about before? I couldn't find a thread for it. Thanks!
If I understand what you are asking, it is possible to create a 100x400 town, however, it would have to be done with two towns, not just one, each being 100x200. It may be easier for me to take a look at your area sometime. I should be on later this evening, just watch for me and pm or mail me!
You cannot. Each dimension must be minimum of 100 blocks and a maximum of 205 blocks (see Jamie's post in screenie). You could be the first on the server to get a 205x205 town.
