To add to what Kudo said, you can also use the "ignore" feature of the forum to make anyone whose posts you don't want to read disappear. Just view their profile and then click on the link that says "Add X To Your Ignore List". After that, their posts will be gone, so you don't have to see them anymore. You can review your ignore list anytime from the user control panel
Ignoring trolls is usually a better response than fighting with them as they are looking for extra attention.
Also, we are considering some other possible moderators, so more help may be on the way for the two hardest working mods on JF.
(Edit) Kudo: Don't request to be a Mod in this, or any, thread. Eki will come to you. ^^
