Just picking up on this comment made by Andy in the ArtRage Facebook Group thread -
re - We do very much appreciate enthusiastic ArtRage users spreading the word. One of the problems of keeping the price of ArtRage so low is that our advertising budget approaches Zero. So we definitely rely on word-of-mouth advertising.
Hey Andy, there's already links to your site there, but I'll happily add a splash page to my own infrequently visited site if you like. I'd be delighted to help promo the software. It won't be front page, but I'll link all the other pages to it so that folk stumble across it. I could add a counter to see just how effective it's being too, for feedback purposes.
If other fans consented to do the same on theirs you may quickly have some viral marketing going on. I would suggest you come up with an authorised image/poster/banner that we can all use.
Maybe to personalise it for each site, we could all have a few examples of images done in AR alongside the approved bit.
Just let me know if you think it's worth trying.
