Well, I believe it's only fair to charge a small fee to run the sever as you can't continue running it from your pockets.

However, I don't think I go with the 5% fee for scheduled posts. That's rather too much if you ask me. Yes, taking a percentage would again be fair, but pegging it at 5% is what I have a slight issue with.

But then, this is just my opinion on the issue.
