So the guys from Triqle have been in touch with me. It seems that most of the things I could dream of are coming along. This includes categories (that has been done), features such as timing for the carousel and cleaning of the system messages.
I have to take back my concern about custom URLs. Of course, I am free to set up whatever I want on my DNS servers, so I can easily do a redirect. Probably, routing your own sub-domain to their DNS servers and having a transparent solution might be even prettier, but I see that that’s getting difficult on their side.
Also, external content is coming. I don’t see anything that would be missing if these features were implemented. And as I said, I can’t wait to use Triqle because it’s simply a great solution. Just think about how much value you add to your event, how much time you save and how easily you can impress your clients.
