fbossuyt,
No, the Form Helper plugin is only good for Editing an entry.
The Weblog:Entries loop has to be wrapped around the Form Helper loop/tags.
In that case, if you were to access this template to create a new entry, it would load all your entries into that template… it’d be pretty messy
If you’re unaware of the EE Stand Alone Entry Form, this is what it’d be for (creating new entries on the front-end)
