            const $editor = $editorWrapper.find('.editor');
            $editor.html(Handlebars.compile(editorTpl)({send: true}));
            const editor = _initEditor($editor.find('.editor textarea')[0]);

            /** init the avatar of authenticated user */
            $.get(_url(urls['oauth.user'])).done(({id, avatar_url}) => {
                $contentWrapper.find('.user-avatar').on('load', function () {
