Purge: ?

[theetrain]

How about we send out a purge notice for the following channels, giving people 1 week to move to their umbrella channel?

• #ux -> #design (canned)
• #security, #science -> #technology (canned)
• [ ] #apis -> #programming
• [x] #oakville -> #toronto
• #making -> #homeautomation (rename to #diy) (canned)

security #science and #technology should remain apart

making & #automation, not sold on that change.
