 Please keep in mind that many of Wagtail's core and expert developers prefer to handle support queries through [Stack Overflow](https://stackoverflow.com/questions/tagged/wagtail), since the non-realtime format encourages more structured and fully-formed questions. Asking questions on Stack Overflow requires more up-front effort (see Stack Overflow's advice on [how to ask a good question](https://stackoverflow.com/help/how-to-ask)), but you may well find you get a better response as a result.

+When posting long blocks of code, instead of just creating a standard code block, please use the `+` button below the text box and look for the "Create a text snippet" feature. Text snippets support syntax highlighting and automatic collapsing (when longer than a certain number of lines).
