I dont see wikisource at all in welcome.py , for any language. Has there been discussion on Wikisource about welcome bots , etc.

A simple patch list this can be added using https://tools.wmflabs.org/gerrit-patch-uploader/

We could add 'subst:welcome' as the default for all wikisource ? And bigwelcome as an override for ru.ws.

We would have to ask the community what they want to do. I don't believe that the community finds the tasks too burdensome.

FWIW We don't subst it at enWS, we keep it as an active template.

As a more general comment about welcoming, and from bots.

• people do seem to like the personal welcome, I get numbers of newbies

popping past my talk page afterwards, and from established users often a
thanks, especially at Wikisource.

• stewards have noticed that bot welcomes at problematic account names,

especially with abusive, etc., are a clean-up issue and sometimes quite
messy, so we really recommend a significant delay between join and bot
welcome.

Are subst: of welcome, can that be switchable? At enWS we no longer
substitute.

@dima_st_bk, could you ask the Russian Wikisource community if they want welcome bots on their wiki?

@Billinghurst, welcome.py can have an optional default value for all wikisource sites , and then specific wikitext for each wiki site where that site uses a different syntax for welcoming new users.

if there is no consensus that most wikisource sites want welcome bots, only individual wikisource sites should have a configuration added for only their wiki.
