Having set up a Joomla support forum, you will need to figure out how you will be moderating the debates that will be taking place in the forum. Otherwise there is a risk of the debates getting out of hand. You see, in the absence of a moderator, some of the people who post stuff in the forum may start posting outrageous things. Or some of the forum members may start being very hostile to other members — leading to a situation where people start avoiding the forum. Furthermore, you need moderators to keep debates going on even on forum posts that don’t attract many commentators.
If it is a small Joomla support forum you are running, you can opt to do the moderation by yourself. But you’d still need to have someone to help you, because you can’t be moderating on a 24-hour basis (yet people are likely to keep on posting stuff on the forum on a 24-hour basis).
You can decide to hire people whose main job would be that of moderating the debate on your Joomla support forum. So you can hire people on a full-time basis, to be working in shifts, moderating the debate in the forum. You can actually set up a separate HR portal for your staff. This would be something similar to the cvs myhr employee sign in system: where the moderators would be clocking in, before embarking on their day to day work on the Joomla support forum.
There is yet the other option of using volunteer moderators. You can tap some of the most passionate members of the forum to be moderating the debates there. This approach would be particularly good if you haven’t monetized the forum. And if you have monetized the forum, you can get into a deal where you would be sharing the earnings from the forum with the members who would be helping you in moderating the forum.
