How can i show my screenshot from my characters, so people can discuss or help me build a good team.

This can be a problem if you are using the mobile version of this site because most features in the mobile version are cut off (or maybe I'm wrong and i just don't see them in my browser).

The easiest option is to use the desktop version where all the features are visible.

Take a screenshot (with a built-in or third party tool like LightShot if you are playing a PC version or via an emulator; if you are playing over the phone you have to upload the screenshot on your computer***), then select "Insert Image" from the top menu and you're done.

***I may be wrong about the mobile version, but I didn't find a way to upload screenshots over the phone, so I usually do it via my PC***
