This seems to be a situation where one step is taken forward and another back. Some time ago, I sailed from Newport Yacht Club to Saint Helene. At that time, I could pass through Rollo with no problems but was blocked by a no-public-access region at Starstrider, requiring me to backtrack and sail up the waterway that runs North from Chopsaw to Skains.
Since then, Rollo is blocked, but Linden Labs (presumably) has reserved a narrow corridor along the southern boundary of Starstrider, and a number of similar corridors which do allow one to sail round the West coast of the continent. Which is great. Now if we could just persuade them to stop running their corridors diagonally across regions from corner to corner, forcing skippers to brave the dreaded four-corner-sim-crossing...
I too have attempted to contact "the management" of the Rollo region, but have received no reply. I can understand that they might find it annoying to be hassled over what is really not their problem, but it is a great pity that they can't see their way clear to allowing at least a corridor along the northern edge of the region.
