I was expecting this eventually, but still don't look forward to it. Do any of you feel the same way? What are the main disadvantages of the new site with respect to the old site? Except for a brief trial of the new one several months ago, I've been using the old site continuously, so I've forgotten all the complaints.
The new site is just a disaster. I suspect that the real reason they are ending the classic site is because that is the only way they can force people to use the new one.
It's a bloated pig of all the latest  fads wrapped in a hideous red theme and awful fonts that render equally badly in every browser. I wish web designers cared more about site usability than fun design gimmicks.
I will give them credit for finally bothering to let us edit posts, but this could have been added to the old site a long time ago if they actually cared what the users thought.
I much prefer classic site - it has a much more intuitive interface.
The big problem with the updated site is the speed of loading web pages. On many occasions, the Olympic men's 100metres can be finished faster than accessing a web page on the new site.
Ok, that's it for me. I don't think I will continue doing notebook corrections. It is so much more complicated in the new version than in the classic one. For language corrections I will move to another well-known community. I think I will only use italki for booking online classes (at least until I used up my ITC).
This isn't about visual appearance, it's about software quality. As things stand, I think italki will lose between 10% and 20% of its users, for whom the new forum just plain doesn't work.
I've just gotten back from a road trip and I think italki has made a classic and serious mistake: not testing their new software with real-world technology, and assuming that everyone will be using a fast internet connection on a few up-to-date and fully standard hardware-software platforms.
I was using a three-year-old Kindle Fire Android tablet with Amazon's own "Silk" browser. Not the center of the mainstream, but not anything bizarre. I used hotel wi-fi in perhaps twenty different locations.
The "classic" italki website worked fine everywhere. The new website did not work at all anywhere. The chasing arrows I see for a few seconds here at home never stopped. Maybe it's downloading a humongous amount of data; maybe it's using a spiffy new technology that isn't in a three-year-old browser.
A language learning website should assume that it will have a global audience of users who will be using a wide variety of technology, at a variety of connection speeds, some slow, and should be tested for usability with all of them.
If they can't get the spiffy new software to work properly for people who are using three-year-old off-brand technology, they need to keep the old software up and running and available. In fact, the new site should sense whether your equipment is up to snuff for the brave new Web 2.0 world and redirect you to the classic site if it isn't.
