I clear my cache entirely on a daily basis. I tried testing with IE6, but you have chosen to make the site not compatible with IE6, so that didn't work in many ways (although it still had a single PDLM link, not the split Edit/View links).
I also cleared all *Geo* cookies (which I normally have set to keep) and relogged in and it's still the same.
Before I spend hours on this, could any other standard user who is using Firefox confirm whether they are seeing the single "Linked Alias" or the split "Edit Profile | View Profile" links? Thanks.
