Can't say enough good things about this plugin, and the people behind it. There's no fluff, the plugin does exactly what it's supposed to in a straightforward way. The really amazing part is I had another plugin on my site that was also using the User IDs, and it was clashing with the User ID changer, but the author immediately found a fix for the issue!

Excellent plugin - simple and straightforward and the only one I could find that allowed me complete a mass User id update for an urgent project. Support is outstanding! I asked for two minor changes to assist with my particular project. Code changes were supplied within hours. Highly recommended.

WordPress is not safe, and it will NEVER be 100% safe, unless the site admins take some steps, this plugin takes care of one of those important steps. - We all know that hackers try to attack the useername "admin". But they can also attack the user ID, which the admin account in most cases would be 1, and in some cases 2, 3, etc... (lower numbers). This plugin takes care of that, and it works perfectly. - The second thing that WordPress fails is the fact that it allows the actual usernames to be displayed in public. Thus, if an admin. writes a post, and does not change how his public username will be displayed on the front by his profile page, then everybody will know the admins usernames, thus making this plugin useless, mainly because if the admins pure stupidity. WordPress has to fix this, where the actual usernames are not shown on the front, as many admins are lazy, uninformed, stupid, or all 3!!! GREAT PLUGIN !!! I will be using this with every site that I have.
