(Description box needed!)Later I realized it will only work if the chat partner is online. I would like to send a secure message to an offline person, but don`t know how. Need I download the OTR Keystore then? This friend also didn`t receive my messages at all and I didn`t know that, because no error sign occurred. (See “error prevention”) | ||
*Add contacts: When I added a contact, he showed up in the contact list twice. I deleted one of them… later “both” accounts were gone, so I fully deleted the contact by accident. | |||

*Sending messages: I have no knowledge in computer science, so I would like to have a little explanation about what OTR or this OTR Keystore is. I would like to read easier words, like “start secure messaging” that don`t make me wonder what I am doing.

*Sending messages: Didn`t understand the box that plopped out, when I wanted to import the OTR keystore. (And don`t know what it is for, by the way.) It was only open for a few seconds, so I couldn`t read all of it. After I read it 3 times, I still didn`t found this file, the window wanted to lead me to. | *Sending messages: Didn`t understand the box that plopped out, when I wanted to import the OTR keystore.

*Add contacts: After typing in the name in the contact box, I wanted to click on “invite”. For that I clicked in the red box below, because I intuitively thought, I would come to the interface before. Maybe it is better to place the “invite”-button somewhere in the red box, because you won`t have to click the keypad away then. | *Add contacts: After typing in the name in the contact box, I wanted to click on “invite”.

*Sending messages: I clicked on someone on the contact-list. The message window opened and I typed something. So now, to write another person, I needed to slide over many people before I got to the “general” contact list, where all friends are listed. I think having the general list in one slide is way easier. | *Sending messages: I clicked on someone on the contact-list. The message window opened and I typed something.
