it's cos ZFGC is so crazy and fast-paced that you just have to keep checking back. If you don't check back hourly, ZFGC could have changed address, deleted your inactive account, merged with another forum, been hacked, had a riot, blown up, or found true love.
It's like a baby kid, you can't just leave it on it's own - you have to keep checking back on it to see it's ok.
