On the wrong team?

I was under the impression that i was on th XS team on seti@home, but i didn't find my name anywhere on the member list.
Went into my seti@home account page and discovered that i was member of xtremesystems.org, not the team connected with this team. A previous team perhaps?
Anyway, i left the defunct and almost empty xs.org team and tried to join this current XS team, but it wouldn't let me. The "join" button simply was not there.
I don't know if i need an invitation or if the team leader needs to fix it manually?

Any help would be greatly appreciated :)

Problem resolved :)

yeah i could use an invite too :J
