As you will come to know, I am an avid Fluxbox user ... Fluxbox is closely based on Blackbox.
Currently, have both Mint-9 Fluxbox LTS and LMDE, using Fluxbox.
I also, do not use Windows or any other MS product.
I have no distaste for MS or those that do use it.
You have to use what works for you and meets your computer needs.
I have searched the internets and can find no forums for Fluxbox - and LostintheBox being the only Forum for Blackbox.
Fluxbox is still closely based on Blackbox. Some say that, Fluxbox is the natural progression of Blackbox.
Fluxbox is a basic Blackbox; with a few more things added for user-friendliness.
Not to take anything away from the base-Blackbox build ... the BB-Devs did an awesome job.
I use many of the BB scripts, themes/styles and apps with Flux -- they seems to be pretty much forward and backward compatible.
Openbox, was also, based on Blackbox but has grown more apart/distant from the BB-base, with using and building it's own configs and apps.
Although, Openbox seems to be growing in popularity -- it is not as well documented as Fluxbox is.
In the spirit of 'growing' the LostintheBox Forum, we have added a Section to the Forum specifically for Fluxbox.
I would like to see the LostintheBox Forums become, "the place to go" for everything Blackbox and Fluxbox related.
