Will,
I am in 100% agreeement with these concerns.
The site performance in some ways can be understood as a simple lack of needed hardware, as it does appear to be tied to times of heavy site activitiy.
The pages that become inaccessiable is something that in my option is a major issue. I will typically every day or so try to go to the forum, the URL will change but the homepage is the only page that displays. This happens for ALL pages that I tried to visit.
The forum, is by far the most concerning issue in my opinion. As most know I am an active participant in the community here, with over 4K posts in under a year of posting here. The lack of e-mail notifications alone is very fustrating as I find it hard to follow through when helping people with issues here on the forums as I typically miss replies since I don't get notifications. It would be higly impactical for me to try and use "my posts" to keep up as well.
It would be great to get some information from the corporation on these issues, I have no doubt that these items are being researched/worked on but I really think with as major of issues as these are that they need to be publicly addressed BEFORE they are fixed, at least that way to new visitors of DNN they will know that issues are being resolved, rather than seeing non-functional sites.
