Just so there is no confusion, here is the relevant excerpt from the list rules:
"Suggestions, recommendations and such, to and from professionals and companies are welcome. If you are posting for your own business, please limit ads to once a month and feel free to post your site in the Links area. Company representatives are encouraged to respond to legit requests for information as long as you identify your connection. IE, don't pretend to be an unconnected customer, there are enough savvy people here that you'll be found out quickly. Just use common sense about replying or people might think you are flogging your business."
The limit on posting is for -ads-, not for responses to requests for information. I'm happy to see company reps posting here.
