One of things I find annoying about PowerShellCommunity forums is that when I spend time answering questions very few people mark them as answered. I can think of a couple ways to resolve this issue:

1. Use a moderator format like MSDN
2. Use a StackOverflow format which encourages active participation including marking responses as answered.

The use of moderators requires the least amount of work as this could be done with no coding changes. Although ideally you would like to have the ability to vote up or down posts and mark posts as proposed answered (like the newer MSDN forums), these are extra features beyond the moderator concept.

I would say for now, create moderators.

I completely agree Chad, great suggestion.  As you can see by me marking this as the accepted answer, it's definitely possible, so now we just need to determine who will be the forum moderators.
