The pagerank checker in axslinks works, and it looks like an elder version of the same damn code. Works on 3 different hosts that I've tested it on - if it doesn't work for you, there's probably other problems with your server. If it does work for you, feel free to dump the cash to darksoul, because I stole it from his, and he got it from wherever. :thumbsup
