Since you're new to Paragon Chat, I highly recommend checking out Crashpositron's site for P.C. tips and info, at:
http://www.pchat.life/1. You send tells by typing /tell (plus) the player's name
or, if you're sending a tell to their global name, it would be: /tell @Players Global Name
Or, if you've already invited a player as a Global Friend, you can just open your friends list, click on their Global Name and choose "Chat".
2. For zoning, you can type /mapmenu to get a list of places to go, including Mission Maps (listed under "Other").
You can also check in your powers tray for a little grey button with what looks like a silvery little man with his shadow behind him. That button will pull up your /mapmenu list.
The trains do function now, as do the highway tunnels from one zone to another.
No alignment restrictions for zones: You can bring your Villains to Paragon Chat, your Heros to the Rogue Isles, and everybody to Pocket D (found under "Extradmensional"
3. Check your powers tray, and click the word Powers to see everything that's available to you, including Travel Powers. I believe all the travel powers function as if fully slotted to maximum speed.
You can make as many characters and costumes as you like. Be sure to Save the Costumes while in Icon, in case you want to swap them in and out later.
Always feel free to give a shout out in the Paragon Chat channel with any questions. The community is just as helpful as it always was.
And - WELCOME to Paragon Chat.
