I got StarCraft around 1998. From the second my brother told me it had a map editor (his friends had it), I know I would be in that thing for many years. The second we installed it (and after he was on it forever), I went into Campaign Editor. (I remember not being able to figure out how to change terrain. Would never have thought of "New" untill I clicked it to start a new map)
I remember learning triggers from Mixed Turret Defence. I went through it (this is where most people go "Huh?!". I looked through, Saw each thing like "Player brings unit to location". When I wanted to learn something, that was my instruction manual. I would look it up in there, then play the game and wait for that to happen.
*Years later; During March of 2005. Found SEN*
Googling how to do something. Found SEN tutorials, GlitchGuide (by DK), and some other nice things here.
By chance I came across the Monopoly Production thread, and at the time (before the map got corrupted, and me too lazy to fix it) I was making a monopoly map. So I tried posting (never had been to a forum before), it said I needed to register.
So I registered, posted, then just by boredom went around exploring the forums (I like exploring things

), I was like "omg dis ez t3h Über1337 syt! i guna viset her fr EVR"
One thing I had a great interest in was the extended terrain, because before joining I was testing out putting costal cliff tiles mixed with normal cliff tiles, making larger cliffs. I had not realized there was so much more you could do.
The "Garbage" forum (as it was called then) was interesting, because there were "forum games" that gave you something to do while you were waiting for a reply to a topic.
And the map making assistance forum I thought was great, because I could share my knowlegde, and gain knowledge from others.
*O)FaRTy1billion keeps going on about all the forums and there Überness And that is how I found SEN; Google.

I typed staredit.net in the link bar wondering if there's anything StarEdit-related here.
That is the best way I have ever heard.
