change of user ID in mylot

I don't think you can change your user name in mylot. But to confirm this, you better ask help from mylot members, by sendin them a message. Just read the guidelines once, i think there you'l find more help regarding this. The guidelines option is there on the bottom of the mylot page.

First try going to the sidebar and look for "edit your preferences". You may be able to change your user name there as you can also change your avatar photo and change any links you may want to update. Give it a try and see if it works for you.

I don't think it's possible to change it. Once you have it, you have it. It's also a part of your referral link, and your own unique ID. People need to think really hard before selecting user names and IDs for sites like this. You can change your avatar, but I don't think you can change your user ID.
