It let me edit my signature after 11 posts, so I think I now hold the record.
However, I tried pasting the banner thing in the signature and even though it showed up in the "preview" I don't see it in any of my old posts. So, maybe I have to have 15 posts for it to appear? (I notice that the URL part of the banner shows up, but the image is nowhere to be seen....)
Oh well, I haven't quit analogs yet, but I will, just as soon as my 510 arrives! And then I'll really make an effort to understand this banner thing that seems to work so well for others (at least those who have had a moderator step in and fix it!)...
Never mind, I went to the smokefreequitmeter site and got this cheesy one that at least works...
