Thre is currently an issue with accessing the humm.tv forum:
"The server is temporarily unable to service your request due to the site owner reaching his/her bandwidth limit. Please try again later. "

The wiki and software download side if it is still OK. (http://wiki.hummy.tv/wiki/Main_Page). Although I don't use it I pesume that RS is also OK as RS has a seperate setup.

Can anyone give any insight to when access will probably be back?
