Tell me, if you're nominating me for a mod, what exactly does a mod need to do? 
If all goes smoothly, nothing.

What moderators typically do (and all we'd be asking you to do) is pretty simple. As I see it, they do the following:
-
Control content in their moderated forum(S). This is the typical mod task, involving splitting topics if a particular tangent really deserves its own topic, stickying (and unstickying) topics when appropriate, locking/unlocking when appropriate (usually locking when a topic is getting out of hand for one reason or another), and at the extreme side of things, modifying or even deleting inappropriate comments, posts, or entire threads. Like I said, if all goes well, you don't have to do a darn thing, but those are the type of things you MAY need/want to step in for.
-
Reporting inappropriate behavior to the admins. Since mods don't (currently, at least) have any direct control over users, any malicious, inappropriate, hurtful, or just plain stupid behavior needs to be dealt with by the admins. This CAN include modifying or deleting certain data, as mentioned above, but most likely will need to be something the admins deal with using the admin tools, possibly all the way up to banning. I don't expect any of our regulars would ever warrant the admins having to step in, but we always need to be on the lookout for bots and less savory characters that might stumble across our boards as they grow and (hopefully) gain a reputation in the LOTR TCG community. Mods are the first
line of defense against internal and exteral attacks.
That's really about it. Just use your heads, warn when appropriate, dabble in mod controls when necessary, and things should work out just fine. It's pretty simple, really.
