Hmm, I like Berlios, I definitely feel much more comfortable on it than on SF (I don't know why, maybe because my nick was already taken on SF when I joined C::B
).
Switching to SF could be a good choice and as long as Berlios is not fully functional it should be taken into consideration. But let's just make some things clear: we switched from SF to Berlios because of the same reason: SF was really unstable then.
So maybe few more "unstable" days is not much comparing to work required to switch back to SF (just imagine all those links requiring update).
Of course if Berlios won't upgrade, I will vote for SF too
