I've just been trying to use Writely to knock up a quick invoice, and I've found some issues with it, particularly its Open Office converter. It seems to add spacing in that you don't have in Writely. I've written a little write up, with screen shots here:

Has anyone else experianced little issues with Writely, such as it adding spaces, not being able to tab etc? I personally think it could be much better, what do you guys think?
