1. There is a storage system. You have to pay 50 gold to unlock it, but it's a one time fee. These storage characters are created all over the place, but only in Post-Searing I beleive.
2. Since a guild consists of members, I don't understand how you would be able to locate a guild anyways...
3. You can use the Whisper chat feature to send a private message to that person as long as you know their name. They can be in a different district or different are altogether.
4. You can make a guild in Post-Searing Ascalon I believe. It costs gold, but since I have never created one I do not recall exact finance. There are prices for initial guild creation, guild cape, and guild hall.
