The software I use to collect payments and manage accounts is called aMember Pro. This software requires you to create an account (username and password) associated with this site before paying and retrieving the theme. I considered using a service that would just deliver the product on receipt of payment but the problem with that method is it lacks an easy way to deliver future updates of the theme.

When Tumblr releases a new feature I want to add that to Primo and be able to distribute it with ease (the feature in question being relevant and useful of course). This is where aMember Pro shines. What it allows me to do is set up a section on my site that is accessible only to those who have paid for it (hence the account creation); so when an update to Primo is released, previous customers just login to their account to get the latest copy.

Primo uses the latest and greatest CSS functionality to achieve effects like rounded corners. This reduces page size and image overhead, but it also means that corners won't be rounded in Internet Explorer, Opera and outdated versions of Firefox. However, the site will in no way appear “broken,” it just won't have rounded corners.

If this is a deal breaker I understand but I would encourage you to ponder a couple things:

• Future versions of Internet Explorer, Opera and nay I say any and every browser will support advanced CSS, especially rounded corners functionality.
• The general understanding in the community of web designers is that websites don't have to look exactly the same in every browser, nor do they have to be experienced in exactly the same way.
