I think this is the subject line. "Introduction"

Hello, people. I am the sarcastic Sir_Biden_XVII. I'm not new to Minecraft, but I am new to forums and posting and all that jazz. I assume this will be the body text of the "post." Why does "Minecraft" have the red squiggly line under it on a Minecraft Forum?

welcome.... to answer your question, "Minecraft" isn't a typical name like Samsung or Dell, it's a compound word containing "Mine" and "Craft" so the spell checker sees it and assumes you forgot to add a space between the words. The code used to create the actual forums comes from Here, and it's just a general forum code and not a Minecraft specific code which is why they didn't care enough to recognize it.

I think I'll wait until I can remember enough about myself to make a proper introduction.
For now, stay classy.
