Hi. I'm DannyS712.
If you need to reach me and I haven't used my local user talk page, please see my meta talk page at m:User talk:DannyS712.
I write user scripts, and may make one for you if you ask me to. I wrote m:User:DannyS712/Global watchlist.js, which creates a basic global watchlist, and then converted it to a proper extension as part of a grant from the WMF; see the extension documentation. Try it out: m:Special:GlobalWatchlist.
Global account information: m:Special:CentralAuth/DannyS712.
