2. Kickpad no longer operate as an IDO "launchpad" but a platform for receiving airdrops from new Cryptocurrency launches. Therefore it should be classed as removed from this list. In the absence of 'Kickpad' I would put Tronpad in its place.
I will keep this document up to date with any changes to their systems.
