I`ve been working all these days on a V2 version of the Watchdog (using ChatGPT and DeepSeek AI)... Still running some tests here and there and check if all ok/stable. On this V2 version, calling it AIO - (ALL-IN-ONE) you can see the messages also on Discord and Telegram. Also now not only tells you when someone is entering or leaving your region, but also the SIM position (coordinates x,y,z) and how long they remained on region once they left!! And flags if its a npc in the region!!! O.o
E.g:
Jimmy Olsen entered NORGE (06:32:02 PM GRID TIME) | Pos: 1507, 930, 27
Jimmy Olsen left NORGE (08:23:14 PM GRID TIME) | Last Pos: 1505, 934, 29 and remained for 01h 51min 06sec
-----
Baldur (NPC) entered NORGE (06:28:27 PM GRID TIME) | Pos: 1185, 1243, 47
Baldur (NPC) left NORGE (06:33:07 PM GRID TIME) | Last Pos: 1185, 1243, 47 and remained for 00h 04min 34sec

Will advertise it when its done (will rez a vendor on URBAM MUSEM SIM, of course).
Thx Arielle for the idea. (couldn`t make it work on cell phone as it would require a paid server and API) but what it offers now is similar! Both Telegram and Discord have apps for cell phones and desktops!
Also thx for my friends Xenon, Luke, Crazy, Mc Cracken and Essensual who has been helping me testing it
