eFFecT finished his part.
There's been some changes on MX Discord. I've archived the #stadium_fullspeed channel, which was a community channel run by Flood being used for the project.
There is a new #stadium channel, where fullspeed is welcome alongside other styles, but I don't want to use that for the project. So there's a new #stad_fs_project channel that only participants of the project will be able to use.
Flood told me to delete the project. So I've taken that to mean he's given up on it.
The project has changed hands too many times. So I'll now see it through to completion.
I'm currently looking into possibly merging both versions of the map so nothing is lost. If it's possible, then we'll do that. Otherwise another solution may be reached.
I've got some experience merging tracks though as I've merged many of my own tracks over the years to make longer ones, and also merged individual track parts in community maps to make long maps. So I'm optimistic that it's possible with some work.
Once that's figured out, we'll continue with new parts.
If you're interested in joining the project, you're welcome to volunteer now and we can add you.
Edit: I've also updated the first post in the topic with the current lineup, based on people who have volunteered here in the forum.
