RIP 43things website

I guess all good things have come to an end... :`(

I just logged in to 43 things (which I haven't done so for a few months) and was surprised to find this message. I have this website to thank for so many goals I have achieved over the past 5 (!) years. I shocked myself time and time again when I would review the site every 3-6 months and discovered that I had achieved goals I'd written in there, goals which at that time I didn't think were achievable (at least, not in the short time frame I wanted).

I'm really sad but have to look for another alternative now.

Any ideas?

Did any of you ever use this site?
