Submit a comment and/or join the mailinglist

You can use the form below to submit comments to the new PERCEPS user comments page. You can also use it to join the PERCEPS mailinglist. The mailinglist should be a low traffic list where I announce new releases and patches. Subscribers can also submit bug reports/fixes directly to the list. (This policy may change in the future, depending upon how much traffic the list gets.) If you subscribe to the list, you will be sent a e-mail message requesting confirmation (to prevent others from subscribing you without your knowledge).

I worked hard to make this script robust, but if you get an Internal Server Error or another error screen, please send me e-mail explaining what happened so that I can fix it.
