I have found some great new sites, along with sites I have used previously for light show info. But, while I have used some of these in the past I kept away from the subforums that dealt with RGB related stuff and controllers that I was not going to use as I had LOR (light-o-rama) controllers.
I have also found that these sites have regular users visiting and posting on more than one site, along with companies who advertise their pre-sales across most sites. All are now added to my phone under tapatalk so that i can keep up with everything.
With no futher adieu…
