Really really enjoyed your expression gate tutorial, really good progression and not straight to "let's make an autonomous missile".
Well done!
On another note, you can actually hide the "tool description" in-game, can't remember the command right now, but something like "cl_showtoolinfo", frees up quite a lot of screen space.
Congrats to the wire helper status too
EDIT: Added a link to this thread from the expression gate documentation, also, just wanted to point out that the link in your signature points to a usersubmitted post in this thread, and not the thread itself (not even your post).
