Howdy. I did my best to find this in all of the FAQs, online docs, INSTALL and UPGRADE readmes (which are somewhat out of date) and had no luck.
I just upgraded to 2.14 of Mailman which of course stomped on my nice archive templates which linked to my swish-e searching amongst other things. I've tried editing things in /usr/local/mailman/templates/ but so far these have not taken effect so I am missing something or pipermail is not looking where I think it is looking.
Last time I had to mess with the templates was a long way back so I have forgotten what was required exactly. Since the docs don't help and changing stuff like "archidxhead.html" seems to have no effect, I am asking here.
An expletive or two in my direction followed by directions to where this is documented would be appreciated.
