What I always used to do was I would just click on View your posts
and check if the threads I posted in had any new posts on them.
Additionally, when you are posting and you have the text box open, underneath that box are the three buttons "save draft, preview, submit". Well, the next box under that is the options tab, and in that tab there is an option for "Notify me when a reply is posted" If you check that box, you should get an email when someone posts.
Alternatively, you can set it up so you always get a notification.
Go to your user control panel, board preferences, edit posting options, and then check the box that says "notify me upon replies by default" And then click submit.
Here is a link to that area of the UCP
Hope that helps.
