There's only one Japanese, at the bottom. The two above are Chinese, then Korean. Next up looks like Thai to me, and then I too would say Arabic.

Hmmm not enough characters for me to tell (Chinese vs Japanese), they look similar, though the bottom is quite obvious.

Thai does seem right; i used to go to a Thai restaurant years ago and that writing was very distinctive.

And yes Arabic and Korean.

Just a guess, but I remember some sketchy site redirects from some of the gothic mods. Just a thought, scan them all using Virustotal(google it). Then copy a url to paste into the url scanner of virustotal. Its not perfect, but may save you a headache if it finds any red flags.

You should invest in some sort of diary.

Bomb disposal experts record their efforts, if only to provide clues to the clean-up crew as to what went wrong. Similarly, you would benefit from recording all your steps as you create your new PC gaming-cum-social-media platform. I would recommend using paper, so that you can read the steps when this configuration fails, assuming it will. (Always plan the divorce before the wedding.) That way you will not be stressed if / when it fails. Being stressed leads to bad judgment. (It has a catastrophic effect on memory, for instance, just when one needs to recall the steps that led to the problem in order to extricate oneself from said situation.)

Seriously. Before you do much else —— especially accounts and passwords —— get a hardcopy medium for the stuff you will not remember. You have been warned! =]
