Where is it possible ??

I suggest you look at the 10 ideas we came up with at Oxford Design Jam http://www.designjams.org/wiki/Design_Jam_Oxford#1

I stuggled to be able to select "Saint Michel", I entered it with or without the "-", and the autosuggest couldn't find it.

You could let us select a station on a list or improve your autocomplete mechanism

I've got a javascript alert when I delete a trip, it seams a translation string cannot be found

I use my keybord to create a trip.
I start by typing Issy, go down to the Issy suggestion in the drop down list, hit "return", it's Aeroport Roissy 1 that is selected.

This way if I'm going somewhere early in the morning, I can click on the "Round Trip" button and only give the timing for entering my way back (to the origin)

Some trips aren't just made at some moment of the day. But only on mondays or only on week-ends.
Or even, once every two months (for example, a student who would go back to his parents' once every two weeks).

not only iphone app, also windows mobile and android!

I've heard you have a iPhone app! What about an Android one ;)
By the way, show a link to your app on your website!

It's always good to know a friend with some common interests. I am a violinist, I want to know some musicians.

I take subway from "A" to "D", station "B" and "C" are between "A" and "D"
Then if someone take journey in these stations duplicate with me, for example someone take from "B" to "D" and "B" to "C" , I think I would like to meet these people more than the mates start or end at same station.
That means Submate should include a system like "Journey Planner".
(Sorry my english is very poor, I'm a young Hongkonger)

I signed up initially via your web site at submate.com, using my facebook account, and then downloaded the iphone app later, but now I can't use the iphone app because I don't know my user/pwd. I tried my facebook auth but it gets rejected.

When I travel to school at Columbus Circle, I always take the local 1 train at South Ferry, transfer to an express train at Chambers, and transfer back to the local 1 train at 42nd Street. It saves time.

Taking bus in Hong Kong is as popular as taking metro. It might draw more people to get attention to ur website

skytrain & subway

I take the same train ( RER A) at 8:30am every morning . i would like to meet people in the SAME train . Very important for me :)
