Just on a whim, I recovered my old ICQ number. Found it by searching for the nick I used back then, three years ago.. Yep, Kriatyrr. Luckily I had used my now-spammed-to-death gmx.net email, and not my now-defunct ex-ISP mail, so I managed to retrieve the password too. I had to wade through over nine hundred spam mails to get to the password recovery mail.. should've cleared it out before requesting it, but I wasn't even sure that was the address I had used.
Doubt I'll be on much, though. Number's 60016244 for any interested.
