Hi=)
I would really like to post something under the category "Literature," as OmnipotentEntity did with the very clever "Tips to Writing a Good Limerick." How would I do that? I'm sorry if the answer to this question is glaringly obvious. I'm not entirely technologically inept, but I'm pushing it. I don't really fit, in that regard haha.

It is a blog post. Only administrators can create blog posts (for quality reasons).
If you want to write a blog post, PM it to one of the admins. They will probably add it to the thing. (I think that's how it works)

Pretty much.

What does "PM" mean?

"PM" means "Private Message". It is a standard function on most forums that allows you to communicate with another member on a non-public channel. You can access it on Nerd Paradise by clicking "Messages" in the upper-right hand corner. From there, click "Compose new message" to begin writing a message.
