Woah I'm glad to read that :D Not only is it nice to hear, that something is going open source <3 Now maybe, all the bull**** (sorry, but that is how I see it, when there is an alternative called ignoring) about MultiMan can stop... It really is detrimental for the site/scene, to always be flooded with negative news, or negatively intertwenings in the news.
It was the same with Mathieulh back then... If he was that big a problem (and if he really liked the fame), it would have been better to ignore him then, and either see him release and help, or not.
Maybe not everyone sees it that way, but most would ordinary users most likely think that the scene and sites would be better without, regardless of who it was that started it. (Most likely the more passive users wouldn't even understand or have enough background knowledge, to know what was going on).
It's going to be interesting seeing, how it will affect the other backupmanagers, and to what degree they will incorporate MM features. Most likely, they will stay pure backup, but will have a few releases in a row shortly after MM goes open source, to accomodate for the increased info released to the scene regarding backup managers from Deank.
Regardless of whether you view Iris or MM as the best backupmanager, both of them probably has some useful tweaks and ways of doing things after all, that the other can benefit of, regardless of the manager.
