At this time SIEE is free to use for a limited time.
But, if you would like to make some donations, I wouldn't stop you:)
If you are using my program, it would be expected of you to make that public:)
If you have any questions, suggestions, concerns, send me an IM. I will try to answer all of them:)
It is still in testing phase, so there might be some some bugs
If you find any, please let me know
Please, read the help file.
