As discussed here, I've been going through posts tagged with "ftp", and adding FTP server-specific tags (e.g. "proftpd", "pureftpd", and "vsftpd") where relevant. There are many such posts, and the retagging caused old posts to appear on the front page unnecessarily.

What's the best way to get these old posts retagged, en masse, without causing issues?

I currently have a list 542 posts that I'd like to nominate/suggest for retagging; listing each of those posts here seems a bit much. What's the best way to coordinate such a thing?

Thanks!
