1) Take a minute or two to search the User's Guide. You might not realize that the feature you're requesting already exists.
2) If you're sure the feature doesn't exist, search this forum for any identical or similar feature requests so that duplicates can be avoided. Everyone will appreciate it -- it helps keep things organized.
(If you find an existing topic that matches your request, please feel free to add your voice to it. It helps me know how many people want something. The more people, the higher the priority.)
3) If you post a request that has already been addressed somewhere, don't expect a quick reply -- or any reply!

4) Keep in mind that if we implement your requests, it doesn't entitle you to any profits or royalties! This should be obvious, but we have to say it. Also, anything you post in these forums, especially images/videos, can be used to promote Magic elsewhere -- but we will always credit you

5) Be polite, respectful, and constructive!

We genuinely appreciate your feedback -- it helps make Magic better and better.
Thanks!
Eric
