Technikman,

What type of file were you trying to post.  Here are the allowed file types on the forums:

Allowed file types: jpg jpeg gif zip psd psdata pdf pddata psprobe sur lsm ism isp iss lss pids scm scp scs wfm png ppt csv wmv psreference wav
Maximum Attachment size: 8000 KB

You can also practice posting on the forum's test board.  If you need some help don't be afraid to ask,  there are plenty of people here willing to give advice and direction.

Kevin

Technikman,

The language barrier makes this a little more difficult, so I made a picture to show how I attach files to posts on the forums.  If you are trying to attach a file in the same way and it does not work, then I would say the problem is likely on your end.
