I am a plugin developer for Bukkit. I played around a year ago with programming on a simple plugin. Now I want to finish it, but I am not able to test many of my functions of my program.

I really need **more players** to test some features. I have **one account** with a original Minecraft. So I am able to use the **offline mode**.

Well it also works with my original account. But I can not change the offline name. I just can use the name of my original account. *Means that I only can login with one player on my server because the name is the same.*

I searched in google for a advice, but all of it do not work (because I have a newer version I think) for me.

 - Minecraft Version: 1.7.5
 - Launcher Version: 1.3.11
 - OS: Windows 8.1
 - Bukkit Server Version: 1.7.5-R0.1

I want to login many times on my server. Means I have five Minecraft at once opend!

**Thank you for your help!**
