Heres a link to EN externals, have a look at the milestones in particular the timeline theyre achieved:

Odd. The only difference I managed to spot between our forums is the fact that they don't have to deal with the same 5 - 6 kiddos spamming
each and
every thread they come across with smiley faces and single-sentence replies. As far as ours, every section, every thread, and nearly every post, is full of 'em. Not tough to pick them out either.
Anyhow, in terms of quality players, although some never made it through to Knossos, I'd have to vouch for-
BLT The Conqueror
Shadokin
Aubigrog
KillaC
Praetorian
*Bear*
Cavalier222 (I believe he was #1 among The Immortals for a good bit)
As well as Niko, Whitey, and Exit Strategy.
The rest are far more active among the forums, blabbing off about nothing to be any real threat in-game.
