LGTM, I've granted access. @Quiddity please test!

The fact the one channel differs from the rest annoys me, eventually (pending the discussion at the off site), I plan to rehaul it to match the rest.

@fgiunchedi: You added them in the fashion we add to the #wikimedia-channels, which is via the channel flags, security is controlled via exemption list.

So I've changed his account to match the rest. We can convert secuirty channel to act like the rest, but it should be in a sweeping action to standardize it, rather than one account at a time.

So I removed from the channel flags list, and added to the exemption/ban list to be invite exempt.

Thanks for catching that! https://wikitech.wikimedia.org/wiki/Ops_Clinic_Duty#IRC_channel_access should be updated too to reflect this as that's the guide I followed
