how will you manage porting of all people? Will there be village created in that hub?
Yeah, the idol is already is risen, main crossroads built.
Will we get signpost for crossroad when first travel there as in w3? What about those who doesn't have much agi (trading alts)?
I'm planning to port to different SG and make cupboards, fill them with signs and give coords in the forum. Also people will be able grab crs from the trading center itself. Maybe, if Dis' claim will expand we'll just put crs there. So people could use teleports on our territory. Or like in W3 some villages will out trade center crs on their outer crs. So public would use them. The idol is pretty close to the central SG. So shouldn't be a big problem with teleports.
How are you planning to implement protection of goods and people there?
There will be outer trading area and the internal (with barter stands, protected by brickwall). The protection of barter stands is based on separating them by brickwalls and being selective in choosing users. Like I wouldn't give signs to the barter area since they're mad enough to start stealing and destroying everything inside. There will be guard's vault whereour people will be watching the things going on there I guess. The area should be totally neutral. The ones who'll be agressive towards people will be hunted down. As for us we won't touch even our enemies there untill they'll start attacking or stealing.
