Mart told me that few people had offered any replacement, so there was no little to no choice in what to use as a replacement. Trying to be helpful, I made my own replacement!
(updated: see comments for newer versions and more icons)
It seems to be more meaningful. I made userinfo.gif four pixels smaller, so they are less invasive. They also look good on differently-colored backgrounds; I had made an example but removed it because even though I put a base href in there some idiotic search engine decided to fill up my error log/inbox with 404 errors it caused.
Hope you like.
Note: Yes, I made a matching delcomment.gif, but not the rest of the grey-ish buttons... I just couldn't stand seeing it not match! ;) It's welcome to be used as well...
