Anyone who wants to play, will create their own level, using their usual level style. Some people prefer to use boxes, or certain themes like Space or Garden, or regularly feature a favorite baddie etc. when they create levels. Some people only create easy levels, or brain twisters.
Some of these have become familiar to many of the players, so my thought was that we could create one secret level each, upload it in one thread, and then see who can guess which level was created by which player.
All the levels are posted in one thread, we each create a new folder in our CustomLevels folder where we download the contest levels.
Each time we play and complete (or not, as the case may be) a contest level, we make a note (to ourselves) of who we think created it, and when all the levels are done, we post our answers.
Since we don't want this to get too confusing, we will keep this post only for players who want to participate in this contest, and to make suggestions for rules, etc.
Since this is Saturday, August 21 (my time) I will set the dead-line to "sign up" for Saturday, August 28th (next weekend) This gives everyone plenty of time to sign-up to participate.
We aren't posting levels yet, so this will give everyone time to come up with a level they will use. Try not to deviate from your usual style, or else will be impossible for everyone to guess which level belongs to which player.
Once I have all the names of people who want to participate, I will then start gathering the levels via email. (Only the people who are planning on uploading levels for this contest will be "pm'd" with my email.) You will send me the level via that address, and when I have all the levels, I will upload them into the contest thread where everyone can download them at the same time.
Once you have played all the levels, and figured out which belongs to whom, you send me a list, via the same email address. When I have everyone's list, I'll post them.
Whereas with the Picture Me contest, we were concerned with privacy issues, we kept that private by only sending the outside link to the participants, this contest will allow everyone to download the games, and see the results, even if they aren't participating in the contest. No one gets left out.

Only those who create a level may guess who the creators are and post their answers. Once the answers are posted, then anyone may comment on the levels.
Sound fair to everyone????
Let me reiterate:
1. Sign up to play in this post before Saturday, August 28 at midnight your time.
2. Create one level using your usual style/playing feature. Davimad pointed out that levels should only be created as Classic or Deluxe, not Advanced, as this would give away several creators.
3. I will post a dead-line for you to send me the level
4. Once all levels have been received, I will post them in one thread
5. You will have a timeframe (to be determined later) in which to play and guess the levels.
6. You will then send me your list identifying each of the levels by the deadline (t.b.d.l.)
7. When I have all the lists, I will figure out who's right and who's not, and post the lists, followed by the correct list.
Any questions or suggestions?
