As things stand, the first diary will be up probably on Tuesday, so the rapid transit one on thirsday or Friday.

I've STILL never figured out how to post photos properly

Do you need any help beyond the New User Guide?

Yamanote (which I'm gathering would be called Heavy Metro

Well, categories are blurred... With lots of standing space and an elevated line, it really looks more like a (heavy) metro, but being JR standard and being part of JR East, and not being considered part of the subway network (which is heavy metro), I'd say let's stay with 'rapid transit'. By the way, here is a 2004 list of Japanese (or just Tokyo?) rail lines with weekday ridership over one million, you see that suburban rapid transit beats subways:

1. JR East Tokaido 3,727,115
   
2. JR East Yamanote 3,545,764
   
3. JR East Utsunomiya 3,274,279
   
4. JR East Chuo 3,144,205
   
5. Odakyu Odawara/Enoshima 1,814,000
   
6. JR East Sobu 1,712,764
   
7. Keio Hon 1,286,966
   
8. JR East Joban 1,231,707
   
9. Tokyo Metro Tozai 1,211,718
   
10. JR East Sobu rapid 1,122,271
    
11. Tokyu Denentoshi 1,107,570
    
12. Keikyu Hon 1,103,308
    
13. Tokyu Toyoko 1,069,856
    
14. Tokyo Metro Marunouchi 1,064,464
    
15. Tokyo Metro Hibiya 1,054,272
    
16. Tokyo Metro Chiyoda line 1,050,804
    
17. Tokyo Metro Ginza line 1,002,932

So not many late-seventies-to-present modern trams in Tokyo, then? Maybe in other Japanese cities?
