Click on forums in the top menu bar.
This shows all the available forum categories that you can enter into and comment on. Once you click on one of them you will see all the topics that hve been created under that forum category.
You can do two things in the forums.
1) You can create a new forum topic. Please check that there isn't an existing topic already about the same subject first. Make sure you create it in the general forum category that it belongs in; eg. LAN talk, game talk, patching and versions etc. If you would like to have a whole diffferent category then please email tim on krostech@krostech.biz [1]
2) You can comment on an existing topic. This can be done in two ways also. You can post new reply. Use this if you want to make a comment about the original forum topic. This will go to the bottom of the page.
If you want to reply to someone elses comment then in their comment there will be a reply link. click that and you comment will be threaded below that persons comment and not at the bottom of the page.
