Not Ice, but I saw the question and I can answer that for you as well. RTE is the abbreviation of Rich Text Editor, which is a fancy name for the editing menu that opens when you click the edit button. However, some users have disabled it in favor of the source mode editing window.
Hello. Ice contacted me through the IRC and politely requested that I take down the user boxes you placed, and let you know.
I also, myself, not Ice, wanted to warn you that you should not be editing other people's user profiles unless to correct grammar, images, etc. You're not in trouble or anything, I'm just going to request you don't do it in the future ^^
Ice, I know this is late, but Good Bye. I'm going to miss you a whole lot(Bigger that 3,000,000 lion turtles). I hope you come to visit sometimes. I didn't know you for long, but you made my days on the wiki enjoyable while you were here. My parents say that I'm not allowed to email people I don't actually know :(. So, this is good bye. Gonna miss you... :( Come visit!
Hey guys, wow I have never messages myself before. O=
Anyway, as of right now, I am inactive. I will still be able to see whatever you post on my wall, and you can email me here: Special:EmailUser. For the short three months I was on here, I enjoyed myself. Good bye to all my allies or not allies, and thanks again.
