Like Obsi, I would not want to make sign posts listing warps in my area. I make sign posts for signs, messages and instructions. The key to all my area is exploration. "Seek or you will not find" is the motto (see sorontar.seek). Hence labelling warps to everything is not in line with this.
That said, there are warps to most parts, but not all. On my thread I have provided photos and descriptions to tempt people to come to my area. In some cases I gave warps to get you to good vantage points or general sections. However, I also discuss areas that *don't* have warps or for which I haven't mentioned the corresponding warps. That is done intentionally.
My eventual plan is make a large Scandavian-inspired section. I do not plan to tell you the warps for every troll cave, every fjord, every drakkar longship. I will tell you how to get to the land but it will be up to the players to find them. I don't want to signpost it.
As to the warp thread, yes I think that is as good a signpost as I ever need outside of my thread. I have listed the warps to the main points but more are in my thread.
So no, including a signpost in my area listing my warps is not good. It is contrary to my aim within the creative MC.
