I have tons of space (where my web site would normally be) and rather than waste good space, I'm willing to store any Avatars there. In all cases, credit will be given to whoever sends them to me. (ie. Submitted by:)
If you're okay with my storing the Avatars, my email address is firstname.lastname@example.org and once I start getting them, I'll put an Updates on mm/dd/yyyy note on the initial message of this thread.
