'Any old TM' is TMNF/TMUF as well

so?.. the new TM²-only people won't even have a chance to participate...

Build an fs drift track where no braking is required.

There might be additional rules about how many drifts the track would have to contain - or you'd simply get more points in the theme category the more drifts the track has got.

Then how about uploading a bunch of makroblocks and be like: "ok, only use those" or "use all of them" or something like that?

way more interesting than the old boring 'connect the blocks' theme. ^^

How about build a track that looks like a pile of sh*t but is actually really good?

I'm too lazy to read all of the suggestions So I dunno if it's been written, but I'd like to suggest a time limit themes.
1st one is to build a map up to 30 seconds.
2nd one - build a map longer than 2 or 3 mimutes
And the 3rd one came to my mind. Use only 2 buttons to finish the map.
All the themes've been used in TMU for sure

I don't remember who suggested it, but I like the <20 second laps idea.

Am I the only one getting excited about this already?

no. i check this four times a day.
