I'll give you mine. It's just one of these -
http://rotator.doublebitcoins.com/r/SatoshiCollector - but I'll give you the admin access and you can change all the ref codes to yours forever. I haven't used it in a long time, so it's out of date, but it's just sitting there idle. You can try it in real time and decide on what features you want in a rotator.
I don't like it because there are very few referal earnings from rotators, and many faucets can't be shown in a frame, so I like using a list better. I paid for this, but you can have it for free - just agree to pass it along to someone else if you decide not to keep it. There is a forum there for help if you need it, although the owner seems to be away.
