Your User Profile contains everything you share with other people on Tox. You can open it by clicking the picture in the top left corner. It contains the following settings:
* _Autostart:_ If set, qTox will start when you login on your computer. qTox will also automatically open the profile which was active when you ticked the checkbox, but this only works if your profile isn't encrypted (has no password set).
* _Auto away after (0 to disable):_ After the specified amount of time, qTox will set your status to "Away". A setting of 0 will never change your status.
* _Open window:_ If checked, the qTox window will be opened when you receive a new message. If you use the multiple windows mode, see [Multi Window Mode](#multi-window-mode) for details.
* _Focus window:_ If checked, the qTox window will additionally be focused when you receive a new message.
* _Place groupchats at top of friend list:_ If checked, your groupchats will be at the top of the contacts list instead of being sorted with your other contacts.
* _Multiple windows mode:_ If enabled, the qTox user interface will be split into multiple independent windows. For details see [Multi Window Mode](#multi-window-mode).
* _Open each chat in an individual window:_ If checked, a new window will be opened for every chat you open. If you manually grouped the chat into another window, the window which hosts the chat will be focused.
* _Enable UDP (recommended):_ If enabled, qTox will use TCP and UDP protocols. If disabled, qTox will only use TCP, which lowers the amount of open connections and slightly decreases required bandwidth, but is also slower and puts more load on other network participants.
NoSpam is a feature of Tox that prevents a malicious user from spamming you with friend requests. If you get spammed, enter or generate a new NoSpam value. This will alter your Tox ID. You don't need to tell your existing contacts your new Tox ID, but you have to tell new contacts your new Tox ID. Your Tox ID can be found in your [User Profile](#user-profile).
* _Microphone:_ Set the input volume of your microphone with this slider. When you are talking normally, the displayed volume indicator should be in the green range.
* _Filter audio:_ If enabled, qTox will try to remove noise and echo from your audio input.
* _Video device:_ Select the video device qTox should use for video calls. "None" will show a dummy picture to your chat partner. "Desktop" will stream the content of your screen.
* _Resolution:_ You can select from the available resolutions and frame rates here. Higher resolutions provide more quality, but if the bandwidth of your connection is low, the video may get choppy.
Groupchats are a way to talk with multiple friends at the same time, like when you are standing together in a group. To create a groupchat click the groupchat icon in the bottom left corner and set a name. Now you can invite your contacts by right-clicking on the contact and selecting "Invite to group". Currently, if the last person leaves the chat, it is closed and you have to create a new one. Videochats and file transfers are currently unsupported in groupchats.
Similar to other messaging applications, qTox supports stylized text formatting. Formatting follows [Markdown syntax](https://daringfireball.net/projects/markdown/syntax), thus:
In this mode, qTox will separate its main window into a single contact list and one or multiple chat windows, which allows you to have multiple conversations on your screen at the same time. Additionally you can manually group chats into a window by dragging and dropping them onto each other. This mode can be activated and configured in [settings](#settings).
