Pavatar class
It has been available from my SVN repository for a while, but you can view my pavatar object source using Collaboa; it supports all 3 methods of retrieval and a caching mechanism, as required by the Pavatar 0.3.0 Candidate Recommendation
If anyone finds this useful enough to want to use it, I'm open to licensing suggestions.
Gravatar vs Pavatar
I'm looking to implement an avatar solution for comments; something more than each user just uploading an image.
A while back Geffy mentioned Gravatar, but there have been some reports of outages and closure to new signups. Pavatar looks like an interesting idea - but I'm not sure if caching the avatars (as per the Pavatar Candidate Recommendaton) limits the flexibility of the idea.
What do you guys think - Gravatars or Pavatars?
