Well, this thread is (finally) winding down, but before everyone finally finishes it, I might add 2p worth...
IMO, the forum is well moderated, with reported threads being removed quickly, spam dealt with and things usually kept polite. One of the issues people keep bringing up is that stuff isn't dealt with quickly enough. Maybe there need to be a "back-room system" that gives the front line mods plenty of Autonomy so they can just get on with it, rather than having to ask up-stares before acting? Someone in the mods covered that the mods had to ask up-stares before acting on many things? Why not put in place back-room guidelines, the get amended every time something comes up that isn't already covered. That way, a mod comes across something that they think is not good and can use their discretion and the guidelines to take a more uniform action against that thread/poster on the spot rather than having to do too much consulting... That may speed up "dealing with" times. Also, it may be worth looking into having the reports lead to threads in the mods section such that all mods can see all reports, rather than the report sending a PM to the forum leader, then, again, a more timely action can be taken by the mods... As said above, they are volunteers that do their best in the time they have. Look at what in the currect system isn't working or is slow/inefficient and change the system to fix it. The mods do a good job, but seam at times not to have enough discretion or autonomy to act freely. Give them it with supporting guidelines and they are then able to do their job without wasting their own time
As for immature members, just ignore them. Yes they are an annoyance, but if they are ignored, they'll get bored and go away
Unless said members actually break any rules, there isn't much the mods can do about them without being ridiculed for it. The idea of immaturity is a perception anyway, and not all people with perceive the poster in the same way
If they do break the rule, report and then leave then ignore them.
New users generally start as they need advice. Not all are immature, in fact most aren't (IMO at least). Many bring more advice to the table themselves and hence should get a fair hearing before you opt to ignore them
So, IMO, there isn't a need to mod-bash, they are doing a good job. It may just be a case of look at the systems they have to work under and adjust them. Those that find immature users are ruining the forum may themselves need to adjust, to deal with such members more effectively, i.e. ignore them.
All the best
