But LK, you have to realise - if he allows Gurus Custom Avatars, then seniors would nag for them - then he would have to give CA's to them, then the members would ask for them. etc. It's a never ending circle. Surely, if we did allow Custom Avatars for Gurus, we'd probably have members here spamming this place up just for their post count and Guru status.
All I'm saying, is just keep Custom Avatars for staff members - it's simpler, easier, and also isn't such a load on Daves server (I assume it automatically hits pics themselves - since my logs for my avatar say that it has only been viewed twice - both by me =P)
