I'll stick to .txt for the time being.
I may switch to .pdf in the future, in which case I will convert all my previous uploads as well.
Right now I'm too lazy to download Acrobat and deal with a new format. Not that a lot of people seem to care.
...I'll shut up about filetypes now, sorry for clogging your journal sections with this.
If you have any questions unrelated to that (like requests and stuff), feel free to fire at will.
