Was RFS Water removed from the list? I tried to apply for RFS Water last year, and while it was on this list, it wasn't in the application page dropdown when you actually apply. I emailed YC and asked about it, and was told it would be added shortly.
Looking now, I can't find any trace it ever existed. Was RFS Water deleted? The URL used to be http://www.ycombinator.com/rfs/#water. Thanks!
