The license for Menu Applets Set 6 permits single use only. This means that for web server scripts, such as those using PHP/MySQL/Flash/XML, you can use the software on a single website, and any sub-domains or parked domains of the website. The exception to this are the Flash Components, such as the Datagrid Extensions, which can be used on multiple projects.
You may not re-distribute or re-sell this software under any circumstances. If you are a web service provider with many customers, you can purchase multiple licenses of Menu Applets Set 6 on behalf of your customers, but it should be clear to your users that the software is from TUFaT.com.
You should not take credit for the development of Menu Applets Set 6, or claim copyright ownership over this software.
If this license description is unclear in any way, just use this rule of thumb: I don't want people to attempt to compete with me on the distribution or sale of these scripts. So, if you're doing something which allows people to get this software without first going through TUFaT.com, then you're probably violating the license.
Please remember that I am a single developer who is strongly dependent on sales from TUFaT.com for my livlihood, and upgrades to these scripts - which you get for free with your purchase - depend on the sales volume. Thus, if a lot of people buy script X, then it's very likely to be upgraded a lot more in the months and years to come, and you'll reap the benefits of these upgrades. I generally put 100% of the income from sales back into development.
