Thanks Soupy.
Yes Richy - I just added a new formatting feature to the invoice and quote footer settings.
So you can for example **make text bold** by enclosing it in double stars, __make it underlined__ by enclosing it in underlines etc.
There's a key just to the right of the footer text box in the settings.
Hope that makes sense, let me know if you need any further pointers on this.
