I've added a new step-by-step guide to the tutorial that shows the process involved in designing a map from scratch (link here). This page deals specifically with designing a fjord, although the same basic procedure is applicable to just about any land type. If you want to see screenshots, check out the mini-gallery at the bottom of the tute.
In other business:
L3DT 2.3b is nearly ready for beta testing (probably in the next fortnight).
Following the previous post, it seems
these people most certainly have heard of an exabyte (thanks Ivan).
I've just returned from an unannounced interstate business trip, so I've got at least half a reason for not having replied to e-mails yet.
I still haven't set up a new domain for L3DT, but I'll get right onto it. Soon. Soon-ish.
