I just tried writing a post in IE10 and found out that the carriage return doesn't work in the editor used to write your post!

A quick Google search revealed that this is a known problem when using IE10 to interact with vBulletin (our forum software). There also is a workaround which I'll get to as time permits, but it might take a little while because I'm very busy at my wonderful new software job.

So in the meanwhile, if you are having any trouble posting, just use a different browser, such as Firefox or Chrome.
