Honestly?

I'd like to at least make it so I can override "absUrl" without going through flaming hoops - we can have ponies and stallions for all I care. That would be first on my list.

And since I can't now, perhaps even rename it, "_absUrl", so there's some sort of mnemonic for it being a private method and perhaps a bunch of other things I've learned from the PBP book.

So, yes, I'd like to take over the maintenance of this module, since it does something very useful in my app, it's not being updated, the maintainer isn't answering my emails (anymore - years ago: yes) and it's probably exactly at my level of hacking experience.

And maybe one of these days, I'd like to completely rewrite it, and give it a proper testing suite, etc, etc, etc.

Who's the guy that I have to tap on the shoulder to get the blessing to do this?
