You guys really have an excellent product here. Extremely easy to use, great features and looks great too.

I'm sure you will get lots of users. What type of pricing will you be looking at?

I think you could work on optimising the page updates. Simply swapping the image in the header resulted in a full page reload which added up to almost 1mb! This makes the site seem (slightly)slow and makes it completely inaccessible to dial up users (yes they're still out there! hehe).
