Wazit?

Why, it's an online checker for Furcadia!

And it don't connect to the game server, so no alt name needed.

Easy to use, enter a name in the text area to the right of the Add button, click the button.
Program sets up the name in the list for checking.

Note: Proper spelling of the name is a must, however, spacing and Capitalization is for YOUR benefit, the check system don't care. Pipe spacing is stripped and replaced with regular spacing, so, nyah, don't bother with that either.

To Delete a name, bit strange, Stop it, then double click on the name you want to delete, and say Yes on the confirmation dialog.

The Stop button ceases checking names, and when you restart, it will take a minute to start checking names again. Program pauses for several minutes between checks, name checking is done in a "not quick" manner to prevent overloading system resources.

Requirements, not very many that I can determine, program is only 48k in size, makes very few demands on the operating system, works rather well, on my machine. The names are contained in a TAB delimited text database INI file in the same folder that the program runs from. The format of the file is:
nametouseforcheck(TAB)Name To Display In Program

Gosh, how lazy can you get?
