Unfortunately, we've had a problem with spammers that use the signature option for spam. They are always newbies that post links in their sig, then they leave. This keeps the moderators busy trying to clean them up, which isn't fair. So unfortunately, we felt it was best to go back to the old options which involves brand new members not having signature options.
All new members will not have sig options until either 30 posts or 30 days, which ever comes first. Hopefully it will arrive very quickly
We are sorry for the inconvenience, but spammers spoil it for the rest of us
