Actually if you write on my wall I get an email, so that's the right thing to do. I just checked it today (sometimes I'm too busy to even read emails!).
I've been too busy to do more than just a little building here and there on my own world. Definitely too busy to make maps for people. Dblcut3 is right, there are folks on the official Eden forum. Go to forum.edengame.net, Make an account (use whatever handle and avatar you want), then for maps look in the "Eden General" area for the thread called "People are making maps". Here's the link:
I understand that you want to change what blocks are available in the blocks menu. Indeed, the appearance of the blocks are set by some PNG files which could probably be modified if you either have iOS 5, or a jail-broken device.
The details of your question are nonsensical. It appears that you want to replace "bedrock and weeds and maybe some deleted blocks" with "current one". What is "current one"? Is that a block you made up?
I do have plans to make worlds with custom terrain (commonly called "biomes"), but it's a low priority. I did the snow demo as a practice exercise.
Before I actually post worlds with altered terrain, I want to speak with Ari to find out what he and Steve think about it. It needs to be a voice conversation, not a chat room, because I want to get a good idea for how they feel about such things and I have several questions to ask. It will be tedious to do the whole discussion by typing, and some of the conversation needs to be private.
To answer the second question, yes, I have gotten a brief email from Ari, and I replied to it. He has my phone number but hasn't called or written back.
Hi! Sillyputty (a user on the wiki) is making a building game and is looking for people to help him. He has a decent amount of progress and is using Java Eclipse. He wanted to know if you wanted to help out with it. If you do please message him on the Minecraft PE Wiki.
I have made maps of the top 15 worlds on the popular list, and I am an unofficial assistant to the Direct City team, I make maps for them every month or so. If you make the top 5 or 6 screens on the popular list, let me know.
But I don't have time to make maps for everyone all the time. It requires searching for the world, making sure it's the right version (because everybody uses the same name over and over again and most of them are blown up with TNT), then I have to load it into my iPad, walk around a while to make sure it looks good, then back up the iPad, extract the data file, run the map program, convert the output to JPG or PNG image format, log in to Wikia or Facebook and upload it.
