I am amazed :)
1/ White label? Super easy! I did embed an event to Wordpress page. Simply with iFrame. You can use it in elementor as well with Embed html code widget and I believe in probably every page builder. Nice. It took me approx. 0 seconds to do that.
2/ how easy is to create an event in ViewStub dashboard?. First I had some complaints when I tested the platform. I am still sometimes confused how to navigate when I am inside ViewStub dashboard – but getting used to it :) And to create event is really easy and fast. It takes under a minute (if you already have descripction text and pictures).
3/ Support. People from company seem to be very supportive and helpful. I tested the platform before I bought it and they answered my questions as soon as possible, considering different timezones.
4/ did I mention White leabel :))?
I should mention, that after I redeemed the code, white label wasn't aavailable. I contacted them on Facebook and they explained it takes a while... After a few hours White label was there. great!
5/ Streaming. I already did only a minor short test of virtual event. Cameras to Blackmagic design to OBS Studio on mac and from that connect to ViewStub. So the main horse / connector to ViewStub is OBS. I never used it, never needed, as I am using BlackMagic hardware. But explanations on both ViewStub and OBS web pages were clear enough to me, so setup was done in about two minutes and voi-la, I was streaming :).

I do recommend this deal for sure.
Now my hopes are that we will be able to translate the platform and emails to different languages soon ;)
