Hello, I have been seeing "hackers" more than a few lately. The obvious ones are the ones who "jump" back on the building right after i push them off the edge of a building or when they fall off the edge of the building. Many do it with only "firebird" which doesn't not give any push to the tank itself. I have witnessed one firebird flip back on after a complete flip. When in flipped position, with no angle from the ground, no gun should be able to give enough force for to the tank to flip; but this firebird made himself flip back up. I also noticed some tanks who weren't using any supplies and keep going after 15 shots from "thunder". I started reporting some of the obvious to tell ones, but due to the regulations of "tankionline.com", i will have to have "proof" of the "hacking" to report the account. Now I do know that tankionline will only accept video's uploaded as a youtube video. So i need some sort of screen video recorder that records files in a way that it can be converted to video file that can be uploaded to youtube. If anyone knows of a program that already works for you, please tell. It is preferable if the program is free to download, and if it is please do tell share the weblink. Thank you.
