Okay, let's take this one question at a time:
scarymatic wrote:what is this place ?
This is a forum for SMBX; you can upload your SMBX levels and episodes for others to play, as well as download and play SMBX levels and episodes made by other people.
scarymatic wrote:what is featured episodes on the home ?
It's a list of all the SMBX episodes that have screenshots good enough to convince the forum founder to label them as featured episodes. However, the featured episodes have been discontinued, so no other episodes will be featured.

If you want to play someone else's episode, download it and put the episode's folder in SMBX's "worlds" folder.
If you want to make your own SMBX episode: When you first open SMBX, there are two buttons on the bottom-left of the window: one is labeled "Start Game" and the other is labeled "Level Editor." Click "Level Editor," then click "mode --> World Editor." Don't forget to save the map in a folder within SMBX's "worlds" folder, or it won't show up in "Start Game." If you have more questions, post them here:

I've decided to cancel SMBXville Under Seige. After my 1st Senior year of college, I realized I wouldn't have enough time to devote to finishing my four-level episode. Apologies to those who cared.
My favorite quote on the entire forum:

You autistic some people so much with that statement.
