1. Which of the Exchange Community tools do you currently use? (Blogs, User groups, Exchange websites et al.)
I subscribe to this and several other blogs about Exchange. This is, for me, the best method of keeping in touch with what is going on. I also read several of the microsoft.public and (.de) newsgroups on a regular basis (in particular those for Exchange clustering)
2. Are you currently a member of an active Exchange User group?
I am a member of one but, to date, my experience is that it is a forum for problem questions and answers (which could be better answered in the microsoft.public newsgroups). In the past weeks, i have seen some improvements in terms of news of E12 (which has also been addressed in this blog) and discounts for events or subscriptions.
3. What purpose(s) do you use the Exchange Communities for?
Mostly in terms of gaining knowledge (esp. in terms of best practice). Again, I find RSS subscriptions and newsgroup discussions perfect for this.
4. What would you like to see improved about
Exchange Communities?
Ass Russ commented, more 300 and 400 level content is good. I understand that you are limited to what you can say about roadmap but this is always good to know and, so far, has been excellent on this site.
5. Are you attending Tech Ed 2005?
Nope. Am based in Europe! Ask again for TechNet and ITForum!
