Can you remove the commit logs from the builds page while other stuff is in progress? Lots of people seem to be bad at realizing that something has changed because they don't bother to read the forum, and then they wonder why their week-old build doesn't have new features.
Hmm, what server package are you using at DO? I have a DO server, the $5 package, that I use to run my website, but there's plenty of storage space for downloads and such still.
The 5$ package for hosting which is good, I can't do automated builds on it because it's a bit more resource intensive and higher memory requirements so I have Jenkins automating builds on my local file server and it automatically uploads them to the build dump.
