Kaps_mr2,
Once again, it is a nice idea, but it is not going to happen. Things like this have been discussed before within the Admin group, and they agreed it is not something they will do at this time. There are many issues such as:
1. There is Maintenance (setting up links, etc)
2. The determination of where the money goes (as pointed out, this is an international board)
3. This is a volunteer board, and many of the Administrators are strapped for time as it is
4. Also, we do not want to give the appearance that though this is a free board, people SHOULD donate. It could be easily interpretted as such.
If you would like to donate to a charity of your choice as a give-back to the help you have received here, by all means, do so. You will just have to do it yourself directly.
