Hi Ron..!!!
OK - these are terrific questions. Honestly, just use your best judgement when it comes to "moderating" your Forum. If you think a person is out of line, you can post under theirs or simply contact them through the Private Message option (it's a built in e-mailing program that allows one user to "talk" to another "privatly").
Also - yes, as a "Moderator" in your Forum (Early Lugers (1900-1906) in your case, for example), you can edit or delete posts altogether. You can also make an ADMIN post which will stay at the TOP of your Forum (I'll give an example with this post). You can make any post an ADMIN post by selecting this icon:

at the bottom of any discussion thread...
Anyway - just play with some of these for right now - as you won't "break" anything - Promise!!! [img]eek.gif[/img]
Thanks to you Ron and to all of you!!!
