1) Thanks for the shout outs on my addons. I'm always open for suggestions too.
2) The term CMS is thrown around these forums entirely way too much. XenForo
is a CMS. It lacks a bunch of the content types by default but it is a damn fine "Content Management System". bd Widget Framework adds the one absolute core feature required for a cms and that's customizable blocks. Everything else (your blogs, articles, galleries, etc) will be added in time I'm sure, but it's a very solid CMS to build upon as a developer.
3) I'm working on a shop but I'm sitting on the fence of if it'll released as I'm making it very specific to the needs of
http://xenmods.com and it's strictly for digital goods (zip files, basically replacing fetchapp for myself).
4) I doubt I'll make a full casino, but I may end up making a couple of card games at least against the computer, possibly against other players.
