I second that motion (though I chuckled when Pietro included a question about his own panos in GE within his post for organizing the forum). A lot of the current posts seem to be "my 360 wasn't selected for GE", for which there's not much the rest of us forum members can say. Sometimes, if a link is provided, we can comment on quality and suggest corrections or ideas for why a 360 wasn't selected. However, a lot of the entries seem to boil down to technical issues for some individual member which can only be addressed by 360cities staff.
That said, there are plenty of times when a technical issue might come up because it affects many 360cities members (ex. the ftp server going down or artifacts showing up in processed 360s). That sort of thing is useful.
One possibility is to have a sticky post at the top of the forum explaining basic rules. For example, "Before posting to this forum, please take a moment to determine whether you post might be of general interest to the other 360cities members. Search the forum to see if your issue has been discussed previously. If you have an issue that probably only relates to you (for example, a particular panorama not being selected for Google Earth), please direct your question to the technical support staff at <appropriate address>@
360cities.net."
Another use of sticky posts would be to put common discussions (like lens selection, how many photos around, equipment comparison, etc.) at the top of the list.
I am assuming that google groups can do this sort of "sticky post" that I'm suggesting here. I have seen it in other types of forums. However, a lot of people never read such sticky posts. One drawback of unmoderated forums has always been that the cost of making a post is always much lower than the possible payback (question answered!) and often lower than the cost of searching for a previous answer to the same question.
Actually, that reinforces Pietro's suggestion. If we had a few different forums and some trusted members could be made moderators, we could move (not delete!) topics to appropriate forums when the poster didn't bother to post to the appropriate forum. The message would not be deleted, but moved to an appropriate forum. This lowers the cost of searching for previous threads and so posters are less likely to simply post and hope for the best.
Moderating has its drawback too, of course, including much more committment on the part of the moderators.
