no No NOOO.... keep them coming! Comments and questions like yours are VITAL to get a clear view on what direction the project should go. Keeping the discussion active is important.
I hope more members join these discussions so we have more information about what is important to the community and what we should focus on.
More on focussed on your situation:
- multi domain support for email? Does it exist for NS and is it a true multi domain support or 1 domain and several virtual domain that are connected to the first domain? (still not knowing enough about NS... 
)
- UTM of NS is extensive enough for your case? If not, what is lacking?
As soon you identified features you need: make a feature request! Explain why you need the feature and how you solve it now. add points on how you think (even if you are not a dev) the feature could be implemented, or if there are multiple options, give more options. Then we can all discuss about the feature and the possible solution.
I know you are not doing this but just dropping a line like: "I want THIS FEATURE (and I want it now)" is not helping the project. Explanation and options (some self investigation) is very important to make it possible, or even giving a reason, for others to chip in with ideas, opinions and eventually, code.
