My Pro-forma commentsPro-forma comments script has now gained quite a following (and it - allegedly - just got bust by upgrading to jQuery 1.7.1). This is a personal request to the team to consider adopting it.
Not that I don't wish to keep on maintaining it, but the next step (allowing users to define one global set of comments to be used across all their sites*) is pretty awkward for me to implement "from the outside", but would be comparatively trivial for the team (I believe).
Goes off to fix script...
* Note: I have a beta half-version of this; it requires two separate userscripts, and allows you to push/pull between "local" (site-specific) and "global" storage. And even if I get the global sharing 'properly' working, it would still only be for a given machine.
