Wow, +4 votes in under 24 hours... that's gotta say something...
Well... it is licenced under the GPL, so as long as we follow the rules of that licence, there should really be no complaint against creating a VCS repository, as long as we follow the rules of the GPL - there's something about noting any changes we make, I'll have to look that up.
Actually, truth be told, I've already set up a repository on github and made two small changes to to the code:
The two changes I made are as follows:
setting disabled vote buttons to "button"s rather than disabling them (see this post)
removed (empty($handle) ? '' : $handle.",\n\n"). from qa_send_notification() and added a ^salutation sub instead, allowing plugins to omit or change the salutation of an email as desired - this may be undesired, and I'm happy to revert if so.
What I'd really like to do is get a group of developers familiar enough with the code (and trustworthy enough) to give write permissions to... Scott, Scorch, Gideon... who else?
