There are many, many legitimate reasons why a pilot should operate /r.  And if you fall under one of those, then please ignore the rest of this post.

If your reason for flying /r is something like "mic fright," then consider giving two-way voice a try.  It's much easier on the controllers, you'll get better service during events, and you may find the process much less burdensome than typing and flying.  Don't be afraid to sound like an idiot the first few times.  Trust me when I say it's unavoidable and we all did too. ;-)
