Okay, it took a bit shorter than I expected it to take!
The new, shorter domain for LinkBunch - LinkBun.ch - is now live and accessible to everyone. As mentioned before, the new .ch domain is interchangeable with the older .com domain, so all link bunches made before this with the older domain will work just fine with the new domain.
The logo and text on the website still refer to LinkBunch.com, but that will change in a short while. And while I'm at it, I'll ask you right away: what color do you want the logo in? Post your answers in the comments below! :)
