Several FReepers have tried their hands at that. One of them wound up getting in some trouble for repeated unauth'ed pings and got the zot. It would nice to have a list like that again, I'd suggest maintaining it as an HTML file and make it your profile page, then put a reference to the List of Lists in your tagline. Y'know, hypothetically.
Thanks for the suggestion, but I am not sure I understand what you are proposing. Could you private message in words of one syllable to this computer illiterate. I do have a Profile page, have you ever looked at it?
