Hi,
I have 2 Visualforce pages that I would like to share the 1 controller. The first page which is already connected to the controller is a list, and the second page is a registration form. How would I add the registration form to the controller?
Thank you

Page 1:
<apex:page controller="NFOSController">
    <apex:form >
        <apex:pageBlock >
            <apex:pageBlockTable value="{!accs}" var="a">
                <apex:column value="{!a.Name}"/>
                <apex:column value="{!a.Availability__c}"/>
                <apex:column value="{!a.Number_of_Competitors__c}"/>
                <apex:column value="{!a.Active__c}"/>
            </apex:pageBlockTable>
        </apex:pageBlock>
    </apex:form>
</apex:page>

Controller:
public class NFOSController {

    public List<Division_Space2__c> accs {
        get {
            if (accs == null) accs = [select name, Availability__c, Number_of_Competitors__c, Active__c from Division_Space2__c limit 1000];
            return accs;
        }
        set;
    }
}
