Other...there is a simple saying KISS meaning keep is simple stupid. Most people do not want their emial accounts flooded with every scrap of information.
I would perfer to have the updates that have been implemented. Not what is in the works 12 months down the road. Keep it short, simple and to the point.
Anything more should have hyper links to go to the information, or simply give us an option of what kind of newsletter we would like to recive. Standard, which you have, Short and Sweet, or Let me know everything.
