I'm still not sure what accepting neighbor requests does. I have tested it by accepting 7 neighbors. I see that 3 of them replace 3 existing neighbors (the previous neighbors are dropped out and become friends) and for 4 of them it does nothing.

So why is that important? Well… When e.g. I look in my inbox today I see 89 neighbor requests. Normally I just click through them, but since, in the new system, they replace my existing neighbors I first want to understand what the system does exactly.

	38 FarmVille invitations in my inbox with 2 kinds of messages, they are created on the "tab" Howdy friend! Come be my friend in FarmVille, where you can grow delicious fruits and vegetables on your very own farm! XXX sent a request using FarmVille: Howdy friend! How'd you like to be neighbors? Come join me in FarmVille, where you can grow delicious fruits and vegetables on your very own farm!
	28 FarmVille neighbor requests in my inbox, they are created via the neighbor screen: Howdy friend! How'd you like to be neighbors? Come join me in FarmVille, where you can grow delicious fruits and vegetables on your very own farm! >
	23 Direct Link neighbor requests in my mailbox. They are also created via the neighbor screen but via the reminder system: Click the link below to be [NAME]'s neighbor in FarmVille: http://apps.facebook.com/onthefarm/addneighbor.php?ruid=[CODE]&ref=myneighbors FarmVille is a fun game where you can grow delicious fruits and vegetables on your very own farm!

I have the following questions:

1. what's the difference between the 3 kinds of invites where do they originate from ?
2. what's the difference between the 2 types of "FarmVille invitations" ?
3. when do neighbor get replaced of my own (I'm near 300 neighbors)
4. via what formula or pattern do they get replaced?
5. will I show up as neighbor in other farms even when some persons are no longer my neighbor?
6. are there methods where I show up as neighbor on other farms when they do not show as mine?
7. is there a difference between becoming a Facebook friend and a FarmVille friend? (they all show up in the neighbor screen)

Let's do some tests.

1. Hypothesis: Can only visit Friend once a day

Silverbelle says "then you Neighbor up with someone, you can go visit his farm anytime, but if he's only a Facebook friend who has Farmville installed, you can only access his farm via the Neighbors tab once every 24 hours; it only gives you the "Sarah's farm needs X, would you help her out?" message up there once a day."

So I tested this, just 1 example that proves the opposite should be enough:

My neighbor screen got the following popup above. This is a friend, so not a neighbor. I click the link and I go to his nice sunflower farm. I go back to the main screen and visit again via the link "Go to Robert's farm" and I am there again. So the popup may appear only once but via the link you can visit this farm indefinitely. (I cant see a reason why not).

2. FarmVille Requests Test

	start: I have now 860 friends and 270 neighbors.
	TEST 1 action: I accept the request of 1664719121 (Paula Da Costa) result: FV opens with giftscreen then facebook crash (stalls forever) so… Paula is still there as friend and nothing changed.
	TEST 2 action: I accept the request of http://www.facebook.com/profile.php?id=11805212 (Farrah Glover Hubbard) result: not added to either friend or neighbor list so still starting state (facebook problem?)
	TEST 3 action: I accept the request of http://www.facebook.com/profile.php?id=1477292519 (Myriam Diepart) result:    this is the 1 out of 3 I get the notification… however: Myriam is still friend and nothing changed.
	TEST 4 action: I accept the request of http://www.facebook.com/profile.php?id=100000362012946 result:  still a friend, not a neighbor, nothing changed
