Hi Thomas. The change is live, I tested it on it.ws and it looks good to me. I updated mul:Wikisource:ProofreadPage, is this the only page which refers to pagelist tag? It's rather messy, looks like we should maybe rewrite the extended documentation on the MediaWiki page, so that every info can be found in one place.
For the announcement, I tried registering with the mailing list but for some reason it keeps giving me a "Forbidden" error... can you please send the email for me? Or else I will ask someone on it.ws to do it.
