Wishing to inform the broader community that I have set up a shared project "Wikisource-bot" to undertake archiving of talk pages on English Wikisource (similar to MiszaBot, and ArchiverBot in other places). Presently I am taking the bot through the bot approval process for English Wikisource.
It is also intended that this bot will take over at English Wikisource to do the patrol work that was previously undertaken by JVbot in a past time. John has offered to set the bot up when he has the time.
So the invitation is there for archiving talk pages at other wikis if you have the need. I am happy to do the set up, though would require someone at the local community to usher the bot through any local approvals, or I could look for a global bot right (I am not fully acquainted with all the WSes bot approval processes).
