Is there a dedicated issue tracker? Currently tasks would end up under "MediaWiki-extensions-other" in Phabricator (example: T348573) where no SplitPrivateWiki maintainer or developer would be able to spot them. Thanks!
Topic on Extension talk:SplitPrivateWiki
I'm surprised anyone is even using this, but no, no bug tracker other tha this page.
Although im not sure that bug is relavent as this extension does not use an external db.
