@adeljose ah ok, I get it now, yes that's great if we can give 50 posts for every 20% VP cast. How low will the total VP go after casting all the 50 posts at 20% VP in one session?

I can, without any problem, update this list in alphabetical order.

The problem with update the list with alphabetical order for the second week is, the newly added user will maybe cut the line or going to far behind the list, for example, if the new listed user during the update has his/her name start with letter "A" he/she will get his/her turn back at the first session and will be waiting for a long time before her/his turn coming,
then another scenario, if the same user with the name start with "J" for example and the curator has stopped at users on "I" this user with "J" username, will get to "cut" the line/turn to get upvote compare to the user with the "A" name previously eventhough they have entered the list at the same time.

I think having the users list in alphabetical order can be done, but they will be in the new set of group when curators update the weekly list. For example in the first list group you all have the set of users in alphabetical order like this

@auser
@buser
@cuser
@duser
@esuer

then for the next weekly update list, the list will be arranged like this

1st batch list
@auser
@buser
@cuser
@duser
@esuer

2nd batch list weekly updated
Batch 1
@auser1
@buser1
@cuser1
@duser1
@esuer1

Batch 2
@auser2
@buser2
@cuser2
@duser2
@esuer2

3rd batch list weekly updated
Batch 1
@auser1
@buser1
@cuser1
@duser1
@esuer1

Batch 2
@auser2
@buser2
@cuser2
@duser2
@esuer2

Batch 3
@auser3
@buser3
@cuser3
@duser3
@esuer3

and the list continues to be added in that manner for every weekly update so it goes fair as possible.

I hope you all get the idea..
