To access the start page while logged in use the http://www.bewelcome.org/start URL.
I think it is the only page that is not clickable for logged in members. Is there another one?
Another thing: You posted in the main BW forum. But this question is more meant to go to the volunteers. To avoid messing with the travel and hospitality discussions with technical stuff, we try to post volunteer stuff in the volunteer group. That is, of course, readable for everyone. Just join the group and, next time you got something to say, post there making sure that the "visibility" setting is to "group only".
Also, we got a IRC channel for direct talk on freenode: #bewelcome , and I think there's a Skype channel too if you don't mind running Skype for an opensource project. I don't know if it is very much used.
