When you are submitting a crash report, you can attach logfiles to your post via the Logfile Attachments area under the reply box.

Logfiles attached to a post are uploaded and stored on our server. Your post is then automatically updated to include a "log" tag which displays the first few lines of the logfile in a box. Additionally, a 'Download' link is displayed above the box, which links to the full logfile if desired.

Please use this method to upload log files, as it provides us with the full log file while keeping the forum free of huge lists of errors.
