I discovered a few bugs. Some related with the encodings, some with the mysql. If you tried to use the system before and it did not work please delete the old data and try again. Some bugs I have spotted are unfortunately a bit more complex, and might require a bit of restructuring of the code. In any case for the first time the system generated a readable mindmap. Yes!
The service is still very buggy. It is pre alpha, or similar. For now you can pretty much upload a map, sometimes download it, sometimes visualize it. But not always. You can upload data from delicious, and call the program to make the mind map out of it. But it does not always work, and in general it mostly work when the mind map that wold be generated is quite small. I am doing my best to correct all the above, and make the whole system smooth, but it will take some time. In the meantime, feel free to test it, and give me feedbacks.
