I think anything that might stop people turning up to club nights is a bad thing.

Its better to get new people along to the club and talking to people and finding out about trips before they sign up.

Old crusties can normally sign up via a text, email or talking to someone in the quad anyway.

Also, I suspect, without knowing that if you could sign up online people would either do it late and/or be more likely to pike.

 So I'm not a fan.  But I'm pretty crusty these days.
