I called this forum "my little forum" still before it was downloadable and when I just used it on my website. But actually it's a quite stupid name, isn't it? And as there are a lot of changes anyway in the current version (2.0) we could also give this project a better name. Any suggestions?

I don´t think that it´s necessary to change the name of your forum. A lot of people know the name of this forum and it doesn´t sounds like a good idea to me, because I like the name. Furthermore, it´s still a better name than Simple Forum other others.
