Do know who you do and don't want to encourage to come to your event. Have a plan for discouraging unwanted attendees.

• Do have people in place to act as 'stewards' whose job it is to help protect your guests and discourage disruptive behaviour, or the targeting of individuals by outsiders. Make sure they have good skills at managing hot situations.

• Agree tactics with your stewards about how to manage disruptions of different kinds.

• Do feel confident and assertive about questioning someone you don't know if they arouse your suspicions. Feel confident about rebuffing advances or invitations to other events.

• Don't allow yourself to be manipulated or exploited. For example, don't allow your motives to be questioned in managing the event well.

• Don't give out personal contact details, mobile phone number etc. for yourself, your speakers, or your fellow students.

• Do make sure that responsible people are keeping an eye out for your fellow students; in addition to loud and disruptive heckling, make sure none of your fellow students are quietly being solicited or approached by someone you do not know and trust.

• Do get support before the event, or after if necessary. Speak to your university's 'external-' or 'public relations' or department if you are worried about media issues. Speak to a relevant member of university staff that you feel you can trust if you are concerned about security issues.
