Possible change of login thus nick?

[hecato]

I will like to know if is possible, or I need to register another account.

The only problem that I see with creating 1 from scratch are to link myself with my post and some threads that Im subscribed and that I like to have in a list.

I will like to know if is possible, or I need to register another account.

The only problem that I see with creating 1 from scratch are to link myself with my post and some threads that Im subscribed and that I like to have in a list.

Also 1 extra question, I see that there is no limit in the number of folders that I can have for subscriptions, but actually when adding a subscription, I don't see the new folders (is that a limit?)

According to this no it is not.

Can I change my username?

No. Usernames can not be changed - dashes can not be added, lowercase cannot be made uppercase, etc. However, you may choose to create a new account. The only exceptions to this are extreme cases, such as when a user has been harassed by another user.

Note: If you do make a new account, you will have to transfer all information yourself, as we will not do this for you. Also, we can't transfer your statistics (beans, account age and the like) to the new account.

Will you delete my account for me?

We are sorry to say that account deletions are no longer possible. If you wish for your account to become inactive we recommend you contact an administrator who can remove your email address from the account and change the password to make the account permanently inaccessible. Account deletions that have occurred in the past have made all of those users' posts belong to "unknown" and have made it impossible to track issues. There will be no exceptions to this policy.
