I found a bug that was wrongly assigned to that non-longer existing herd and, then, it was completely ignored. Could its bugzilla account be removed to prevent people from wrongly assigning bugs to them? Or... if I have permissions to do that myself, please let me know about how to do that for not bothering you with this kind of issues in the future :) Thanks
i don't think you can delete accts in bugzilla, you can only update their description if you're on the alias, you can just go to bugs.g.o and request the pw for the acct, then check the e-mail & login to update it yourself
overall process is covered in bug 585990. this bug tracks only the execution of the one account in question now.
Disabled and changed mail to app-dicts+disabled@gentoo.org. Please take a look at the few bugs with it in CC.
