I've seen a couple of people mention that there are problems going on with pet profiles, and there is that ominous message about losing your coding on the editing page... is it completely borked? I was on hiatus for awhile and I think I may have missed this, and I want to make sure before I jump into it, so I don't break something :(
I've never had any problems with it, personally, and I've been fiddling with mine fairly consistently for a while now. Just copy your description before you hit submit or save it to a separate document in case there is some kind of error.
