With pidgin you can use Telegram but be sure to change setting of downloading history. Change it to two days and try to unflag unneccesary contacts or else it will take ages for the app to update messages and it will open all contacts as default. I have been able to send messages with web telegram. But you have to put the phone number and let the app choose the country, not vice versa. And it takes about 10 minutes to generate the key and then you have 2 minutes to put the code they send via sms. Used with opera 12 testing. But it does not save the key so can't really use that way unless someone figures out how to save the key. Have thought that could it be possible to use web telegram with netsurf browser through easy debbie.
