I’ve noticed that when using Perch, and some of the third-party text editors that are available, I frequently run into the term Textile in replace of HTML. Typically, I see it like this:
When using an editor, instead of writing raw html tags like Bold Text and assuming Textile is enabled (“true”) you can use asterisks instead, BoldText. It’s less geeky for your clients and hopefully more user-friendly. You can do quite a bit with Textile but it’s not intended to do everything.
