hi all my name is romuotik iam a technical of mikrotik in egypt
iam using mikrotik user manger but some proplem see it when i genrat batch user is a sequential
I need to bring users generated sequentially
ex:
user: user3000001
pass: cdfhsyj
user: user3000002
pass: rdhnvk
user: user3000003
pass: fhrkgnc
So that when generating the names of users be sequenced in order to be printed on cards distributed to customers and be a serial cards
Hi There
I am sorry this is not advice. 
I just need to be sure I understand your problem correctly. so I will re-phrase it.
You want usernames to be generated in a secuential fasion when you create a user by just adding 1 user at a time.
Do I understand you correctly?
If so? you want a set-able “default” username in User Manager that comes up as you want to create a single new user, AND the new username must “increace” to the next “number” from the previosly created one?
I can not use CLI yet, but I know the UM I use do not even do that when I use “Batch” user add.
I would like to put serial numbers on vouchers 
ya i need that plz i need update user manger to genrat users with serial numpers
maybe this thread give you idea, http://forum.mikrotik.com/t/automatically-generate-a-list-of-hotspot-user/25777/7
