I do apologise for the tone of my previous letters. I may be willing to volunteer to maintain the older extensions. I have been reading through the source but I still a novice on internals and how everything works. I would certainly like to contribute more to the project and become more of an X internals expert.

I do respect and admire your contributions and work on the X system and again please disregard the tone of my previous letter. 

On the upside, memory leak aside, I have seen an improvement in compatability with Savage. I used to have severe problems with it only working with a 640x480 resolution on xfree86 but now its pretty much autoconfiguring so less hassle than with XFree86. I have been using this Savage adapter since xfree86 days in 2002 and indeed things are much improved under in general. The DRI work is also good and the work to add the composite, render and so on is commendable and has improved the state of the X desktop. I would certainly like to help improve the features and capability of the X system to make it the most advanced and backward compatable window system in the world.

Best Wishes,
David Jackson
