Hey y’all! It appears http://xom.montres.org.uk:8080/ is down. Anywhere I could play variants nowadays? Thanks!
https://underhound.eu:8080/#lobby has bcrawl (and Zot Defence, but it doesn’t seem to work in 0.16 or trunk)
WebTiles - Dungeon Crawl Stone Soup has stoat soup
these are the only “officially” hosted forks, as far as I’m aware, but I’m sure there are more out there on other sites. (Actually, I might have forgotten some.)
crawl.yiuf.org (NA) and crawl.nemelex.cards (Korea) have the same package as XOM did, as I believe does http://cco.crawlcosplay.org/ (how did that escape my head, IDK).
crawl.montres.org.uk has console Stoat Soup.
