Well, I am quite sure you are a recruiter yourself. Like the usual, see if the member is qualified for admittance, Tier 7+ and has a mic. If they don't have a mic, I usually let them through saying you have around 2-3 weeks to get a mic to participate in any serious clan activities.
Wince you have asked them that, send them to an admin if one of them is online. If none of them are online, just let him in and notify an admin that he does need approval. I'm just to make a recruitment guide myself.
