Hello.
Firstly, I would like to say that atleast once in a day, my fellow ARA workers or I recieve a PM to support the hoster's event (make barricades). If you really want support in an event please head to 
here and make an application regarding your event. The ARA staff will review your application for the event as soon as possible and decide.
Use this form in the application:
[b]Name In Game:[/b]
[b]Your Phone Number:[/b]
[b]Is this event hosted by any Event Organization? If yes which one?[/b]
[b]What kind of event your hosting?:[/b]
[b]What is the location of the event?:[/b]
[b]Date and time of the server?(server time):[/b]
[b]Where you want the barriers placed?[/b]
