I've seen a number of ublas questions here recently (including my own); is there difficulty in joining the ublas-dev list on yahoo groups? (Daniel Elliot also commented on this last week.) My membership application there is pending still - its only been 2 days for me but still no posts on ublas from Daniel. (Has everyone in the US gone on holiday to avoid the election coverage?). Could the registration process at ublas-dev in yahoo groups be relaxed as there do appear to be measures to stop spambots autoregistering.
