No problem; the name of the games are fairly similar, so it is not uncommon to get topics in the wrong section. Only a forum moderator (Lynn) can move a post, though usually that is not required.
At the top right of each post (in the blue bar with the topic title, number and date) there are 3 buttons: Edit, Reply and Quite. If you hit the Edit button, it will allow you to change a post (to make additions or corrections) up to 48 hours after it was posted. Below the text edit box there are a bunch of smilies, and below that are a couple checkboxes and buttons near the bottom of the page to 'change this post' or 'delete this post'.
