In case you haven’t looked at the Dopplr FAQ, here are some of the user tips you may have missed:

How do I add trips?
Click on “Add a Trip” (upper right on your home page). Then fill out the form and you’re off! You can also click on a city name and add a trip from there.

How do I invite people to see my travels?
Click on “Invite” at the top of the page—then fill in the form. (From time to time we may close off further invitations in order to keep the site running smoothly while we build its capabilities.)

How do I find out which friends and colleagues are using Dopplr?
Type a name of someone into the search box. Try just the first name if you want; we’ll show you everyone by that name who’s using the site. When you click on a name, you’ll be invited to make that person a “fellow traveller” who can see your trips. You can also browse the icons below the trips of people who have let you see their schedules. Click on their names, and if you’re not already sharing your trips with them you’ll be able to start.

How do I see trips of people I know?
This is entirely opt-in, but from one direction only. So they have to invite you. But even if someone else doesn’t invite you to see their travels, you’re free to invite them to see yours.

How can I un-invite people?
You can’t remove them from the service, but you can stop sharing your trips with them. Go to “Manage connections” at the top of the page and select the “Who can see your trips” tab. Then click on “Stop sharing” and they’ll stop seeing your trips. (They will not be notified—your trips will simply stop appearing on their list of travellers.)

Can I do this with more than one person at a time?
Yes. There’s a check-box next to every traveller’s name, and a pull-down menu at the bottom that lets you perform the same action on the people you select.

How can I stop seeing someone else’s trips temporarily?
Go to “Manage connections” at the top of the page and select the “Whose trips you can see” tab. Then click on “Mute” and you’ll stop seeing their trips. (They will not be notified—their trips will simply stop appearing on your list of travellers.)

Can I do this with more than one person at a time?
Yes. There’s a check-box next to every traveller’s name, and a pull-down menu at the bottom that lets you perform the same action on the people you select.

Several people have let me see their trips, but am I required to share mine with them?
No, you’re not obliged to share your trips with anyone. Of course, at some point they may decide to stop sharing their trips with you.

How can I know when my friends are visiting my town?
Click on your home city from your home page. Dopplr will tell you which of your travellers are visiting, and will also note when if you’ll be away during the entire time that one or more of them are going to around.

How do I change my home city?
Type the name of a place into the text-entry rectangle near the top of the page, and see if the city is listed. If it is, click on it. You’ll see a link that says “Change your home city to {whatever you’ve selected}” — click that, then click the confirmation button {”Yes”} and your home city will be changed.

Where does the data go? Who controls it?
We intend to have policies that are protective of your privacy, and are working on them now. If you don’t like what the policy says when we post it, we promise to delete every scrap of information about you from our server. (We can’t control what your friends may have written down, of course. But then again, they’re your friends, right?)
