Well I guess I'd better get to posting. Please edit as necessary.
*How does the Support process work?
Please start up a Support ticket here: [link]
Within a couple of hours after contacting Support you should receive an automatic receipt confirmation email. If it goes into your spam folder set the filter to allow the sender.
The tickets are set up to close automatically every few days. When that happens you will receive an automatic notification saying essentially "Due to lack of communication the ticket has been closed. ... To reopen the ticket reply to this email." This is nothing to be concerned about, just reply to the email and the ticket will be re-opened. You may or may not go through that loop more than once.
Do not send Support emails during the interim unless you are replying to one of theirs or you need to send them additional information. Every time you send them an email otherwise it puts you back to the end of the queue, much like hanging up and re-dialing a phone customer service line.
*I purchased through PayPal, why isn't my software available yet?
[Explain PayPal delay, however exactly that works.]
*Can I uninstall Impulse?
Impulse continues to be required under any of the following circumstances:
Games remain installed which were installed through Impulse.
Object Dock software or other Stardock applications remain which were installed through Impulse. Impulse is required to properly uninstall those applications. Please note that updates made through the MyProducts page [Always/Typically/Frequently/Occasionally(?)] require the uninstallation of the previous version, and if that previous version was installed through Impulse, Impulse will be required to uninstall it.
Installing or re-installing any software which was download or archived (backed up) through Impulse. Please be aware that some discontinued software may not be available through any subsequent distributions systems.
I'm sure I'll come up with more.
