The update to Community Sources 3.85 changes the source url for the BigBoss source. There are some hosting issues. So, if you are have problems downloading apps from the BigBoss source, make sure you update to version 3.85 of Community Sources.
Update: The update to version 3.85 solves a DNS issue that BigBoss was having. Apparently his DNS company decided to block his domain name – making is his email, website and repository go down. So, the update to Community Source make some changes so that BigBoss’s stuff will work again. If you would like to contact BigBoss, his new email address is email@example.com. Also, if you update your Community Source and the BigBoss repo shows up under Untitled Source, keep refreshing your sources until it shows up under Community Sources again.
