Planned services (wishlist)

schilly: who wishes this and did define those purposes based on what discussion?

backup

• purpose: backup between remote hosts, local backups can be destroyed
  • schilly: backup of what?

stats

• purpose: stop feeding google-analytics database
  • schilly: strong objection, we have a long time history stored there and it's far better than any other tools

• public stats are here http://www.histats.com/viewstats/?SID=1579950&f=2

  • novoselt: horrific page - I thought such blinking adds are a thing of the past, had to close it before finding any data

lists

• purpose: do not depend on googlegroups (see what happened with googleID on ask and sagenb)
  • schilly strong objection: what has this to do with google id?
