Poor usability of Sourceforge.net website discourages bug submissions.
* If you don't log on to Sourceforge "correctly" (i.e. you visit the project page to see bugs, then decide to log on to submit one), the log in forgets where you were in the site and resets you back to the homepage.
* Site bizarrely "expires" my password and requires me to reset it, even though I have no access to do anything malicious on the site. The password change process requires about 3 more pageloads than it should, including a step where I have to re-login using the password I just set 5 seconds ago. This is the only website I've used in my life that "expires" passwords.
* Summary fields are extremely narrow, making it nearly impossible to accurately summarize an issue in them.
* Image uploads have a tendency to fail without giving any cause. (Sometimes there's an error message worded so poorly you still don't know what the cause is; sometimes there's no error message.) This is why I've been putting all images associated with my bug reports on my personal domain. WordPress has a very good upload image process to crib from.
* Once a bug is submitted, the user is inundated with dozens of fields, most of which are vaguely labeled and many of which may actually be unused. Also, the "canned response" feature is insultingly named. ("I went through this crappy site to submit a bug only to get a canned response? Gee, thanks.")
If Slashdot's goal is to get suggestions and bug reports from its users, this site is a major impediment to that goal.
