Self-hosted installs have both on every install. Two small features that remove most of the repetitive work from the composer. ## Sets A set is a saved channel selection with its settings. If you always post to the same six channels configured the same way, a set restores that in one click instead of rebuilding it every time. ### Creating one Settings, **Sets**, then build the arrangement in the composer and **Save Set**. While you are building a set, per-channel content editing is disabled: > You can't edit networks when creating a set Sets store the channel selection and its settings, not the text. The text is what changes every time. ### Using one When you start a new post, Postiz offers your sets first. Pick one, or **Continue without set**. ### What sets are good for * One set per client, so their channels come up together. * One set per content type, when a video post and a text post go to different places. * One set for "everything", so a company announcement is one click. ## Signatures A signature is a block of content appended to posts: a call to action, a disclosure, a link to your newsletter. ### Creating one Settings, **Signatures**, then write it. **Auto add signature?** decides whether it is inserted into every new post automatically. Only make one signature auto-add. It is inserted whenever a composer opens, so two would both appear. ### Using one manually The signature button in the composer toolbar inserts any saved signature at the cursor. Useful when the sign-off depends on the post rather than always applying. ### A caution An auto-added signature goes into every new post on every channel, including ones where it does not fit: a hashtag block on LinkedIn, a link on a channel that strips links. If your signature is platform-specific, insert it manually instead, or detach the channel and adjust. See [Global vs per-channel](/general/composer/global-vs-per-channel).
