Sorry! The load on this computer is too great to calculate the results for username. It's only a very little computer and many people are trying to use at the moment. I'm afraid there's nothing I can do to fix this, so please just keep trying.Why do people keep telling me that it's not working for them and quoting this message? Have they tried reading it?
How in the name of God could this message be any clearer? It's a PII 350 with 64Mb of RAM for fuck's sake, of course it can't handle everyone on LJ hammering on it. It's limited to doing 5 trust metric calculations at once, and refuses any further requests. Note that once it has the results for someone, it will store them for three hours, so that's why it seems to work consistently for some people.
If you want to fix this situation, download the source and host a mirror. There is nothing I can do about it.
