Company of Heroes

I'm just wondering how I can make links to things on GR, such as screenshots I have taken or a custom map I have made?

there is a link button at the top of the text editor box when you post on a thread. You have to have the pictures and/or map uploaded to the internet somewhere that you can link to though. I am not sure that you can do that here. If you have already uploaded a map here then just go to your custom map page, copy the url and paste it into the link dialog in your next post/thread.

Maybe I didn't full understand the question, but I hope this helps.

You actually answered the question fairly well. I just found an article on GR of how to do it, and realized I was being stupid in that it is done with the same attachment button as the one used to submit replays. So anyways, thanks for the help.
