Fencer: actually, i haven't complained either: i've simply pointed out a fact. calling tournaments "signed" because they're available for joining doesn't make any sense. at least not in English. "signed" means something has already been signed - past tense...plus in English, "signing" is not the same as "signing up", so - again, in English - "signed" doesn't even come close to meaning "available to be signed up for."

since "available to be signed up for" is way too unwieldy, i agree with Pedro that "available" would be a better choice. "available for signup" would be the clearest, but that's probably a bit long for the purpose too.

wait, i've got it: "joinable." it's kind of a weird word, but its meaning is unmistakable.
