Well basically it was deleted because you didn't include an answer to a topic. We kinda have this rule to try and make every sign-up post contribute as much as possible, because otherwise it's kinda like just saying "I want to join" :p But yeah, a sign-up post is good as long as it includes everything needed as well as a answer to the current topic or just something that relates to the club which isn't completely pointless, so feel free to post a new sign-up post, just as long as you include that ;)
