At Lussumo we make free, open-source software for the web.
And quite cool software too. I found out about Lussumo when I noticed that Joen Asmussen has started a Fauna Forum, as a place to discuss bugs, feature requests and solutions for Fauna. Joen is using Lussumo’s vanilla to power his forum something Michael Heilemann is also doing for the Binary Bonsai Forums.
Seems like almost every wordpress theme has an own forum now and it’s vanilla that is the new hot thing in the forum scene apparently.
Lussumo has also created a web based filebrowser simply called filebrowser which look quite neat!
