How about:
- Entosis linking a vulnerable stargate (new default mode for nullsec gates) for long enough puts it into reinforced mode
- Entosis linking a reinforced stargate for long enough puts it into vulnerable mode
- Jumping through a vulnerable stargate makes you instantly show up in local.
- Jumping through a reinforced stargate does not relay your gate activation to local
- Pilots who are not yet present in local, are reported to local as soon as they (land on grid with? are dscanned by?) (other stargates, players, structures, rats?). balance as desired
