I've spent some time over the last few days gluing maps together. So far people have been building in separate areas that they select in RMBT (our web-based graphical building tool). Combining areas involves first aligning the areas, using some database magic to change all the coordinates in one so the areas are in the right relative points in space. Then I switch the rooms from one area to the other, and if all went well they're hooked up.

In doing this we've started looking at interesting questions like where roads will link up, and in a few cases there have been spaces between areas and we've had discussions on what to do with them. This has led to some interesting new ideas, though here for much smaller areas of space than the major areas that have been written.

I've also been working on a faster version of RMBT: I have a prototype that loads in 1/3 of the time, but its read-only. The faster version will be just as fast but with full functionality. If you choose the largest map size some areas take 45 seconds to load so this is a fairly major speedup.
