I would have gladly paid the $19 to try Site Assist before I paid for that extension. That in reality is the only practical use of the subscriptions. A try before you buy avenue.
Now I'm told that its not a one time charge for activation like the site says. So I take it back ... its not even good for that anymore. Which is too bad. Which is too bad since I was seriously thinking on going that route as I am interested in trying out Sculptor 3 and the Registration one before buying.
Oh well ......
