At least you can see the funny side! I used to do something sort of similar on another site - there were certain posters' names I always had to have purple (meaning I'd read their profiles), so I could find them...it didn't matter that most of them were already on my friends list, so they were easy to find anyway! I don't do it any more...I think I might have stopped after coming back from a months' holiday and realising that it looked fine when everything was blue and I could still find people.

Not sure if that's any help, but I hope you find something that works!

Speaking of rituals, I don't have ocd but I seem to have developed a ritual since coming to halls - every night just before I go to bed, I have to check that the bathroom light's off, my door's locked, my phone's off, my laptop's turned off, my alarm's set and my door's locked...always in that order, and I have to check the door twice or I won't be able to get to sleep. I also have to put everything in my cupboards in the right place, but that's mainly so I can tell if things have gone missing.
