I do have a vision for the long term improvements of our forums even if I have not had time to write about them.
I appreciate your offer but I am too busy with my own agenda and do not have time to coordinate your efforts. If I were making a profit I would be able to spend more time coordinating the efforts of others but I cannot do this right now. I cannot let myself be distracted if I want to succeed at my own plans.
If you send me a patch I will at least look at it but it is very unlikely that I will approve it exactly as you implement it and I do not have time to go back and forth with you on changes to make it acceptable to me.
