Project preview: Comments/suggestions/testing welcome

Sounds really cool!  You should probably just host it here, since it's a short limited sample of your progress.  You can do that by adding an attachment.  There's a button for that at the bottom of the advanced reply menu.  When and if you decide the sample period is done, you can delete the attachment by going to the User Control Panel, clicking Manage Attachments, clicking the box next to the attachment in question, and clicking the delete button at the bottom of that window.  It's pretty much the same as deleting an old private message, actually; this board's attachment system is very well-designed.
EDIT: It's important to note that only people who are logged in will be able to see or download said attachment.
