amigamerl, this is a good new, in my little when i can, i'll help you. pay attention at code of the extensions, it's possible you become crazy
Regarding the software quality: My recommendation is to create extensions by yourself and dont port others extensions into Elxis. By porting a foreigner's extension you do not have the complete control over the extension, you do not know which logical errors the original developer may did, you do not check for bugs and for security holes. It is much better to create smaller extensions by yourself which you will know 100% how they work and you will be able to support them.
