Must resist urge to write a description of "mods", "jimo" or [redacted]

you may be reinventing the wheel.
I would humbly suggest linking to something pretty much all-inclusive such as:
http://badpets.net/Diplomacy/AtoZ/AtoZ.pdf

and then add those definitions that would be Vdip-centric
such as WTA and PPSC and the like

Excellent suggestion!

The glossary I am proposing will be newb-friendly and specific to online dip terminology.

Classic - refers to the original version (map?) of Diplomacy by Allan Calhamer
webDiplomacy points - the "currency" used to buy into a game
Pot - the pool of accumulated buy ins from all players, which are then redistributed at the conclusion of a game
Cancel - refers to the act of negating a game, as if it never happened.
Draw - refers to the conclusion of a game where all remaining players agree to end without anyone winning (see Solo)
Solo - refers to the conclusion of a game where one player achieves the condition for victory. In classic, this refers to the player who reaches 18 centers after a Fall phase is processed.
Tournament - no idea how to define

Some terms when I was starting that were thrown at me and I had to have explained to me-
DMZ- Demilitarized Zone - a space that 2 or more countries have agreed to not move units into. If one country moves into a DMZ'd space, that usually means war.

NAP- Non-Aggression Pact. An agreement between two countries to not attack each other, but not be allies either for the time being.

Thank you! This is helpful. Keep them coming!

EOG--end of game conditions

Your link doesn't work for me. Have you already got 'bouncing' and 'cutting support'? For the real newbies.

Maybe you'll find something interesting here: threadID=32188

I just sent a note to someone and mentioned something that is already part of the linked stuff I gave you above. OTB = a retreat OFF THE BOARD

Sorry, new link:
http://jimbursch.com/webDiplomacy/glossary.php

and a list of every accepted standard game space abbreviations would be nice?

DIAS = Draw Includes All Survivors

Excellent, thanks for the link Guaroz.

Draw: A failure of ambition.
Survive: A failure of talent.
Defeat: An utter failure.
DMZ: An amusing lie to fool the gullible.
NAP: An alliance where you can't quite force yourself to work with the bastard.
Ally: An enemy who can be manipulated into fighting another enemy.
WTO: A version of the game in which you win by crushing your enemies and soloing.
PPSC: A version of the game in which you win by crushing your enemies and soloing.

You're welcome, jimbursch .
That link is very focused on online-diplomacy, actually. Members who seem to have bought a modem just yesterday shouldn't miss it.

Intentional Bounce - Purposely make two units move to the same spot to prevent a single enemy unit from moving there or 'bouncing' as well. (Someone can probably explain that one a little better!)

Unwanted Support - Support that causes a unit to enter a territory when the desired effect was a bounce (see Intentional Bounce).

Eog statement - a post in the gloval chat or the forum that appears at the conclusion of a game where players either offer congratulatory remarks or sling insults at each other

Self Bounce - Two units bouncing belonging to the same power. See Intentional Bounce.

Tap - an attack intended to cut support only, not take the territory in question.

Malicious Support - similar to Unwanted support, except the intent of the supporting (third party) is to create increased friction between two parties which agreed to bounce, in the hopes of disrupting an alliance

Ruffhaus8 = I will make your life a living hell if you do not agree with me*
Defiant = I am attacking you without any reasoning, US of A style*

*A joke, love you both :)
