I'm working on Sigil (that's why this post is here) and it's my maiden project, as you may well notice
In my case, it's a Project Gutenberg ePub file, a theater piece I'm editing (Emilia Galotti, a short German classic). Once I do away with the dashes it'll be almost ready to publish here in MR, though I'll still need to validate it, another thing I'd like to ask how to do.
