Info and suggestion... friend modules

Dear Roople,

I am currently testing on a Drupal 6.6 installation your "dev" release of Avatar Blocks and it works fine.

However, I would like to hear from you about your enlightened opinion. Currently in D6 we have at least three friend management modules:
1. user relationship
2. buddylist / buddilist 2
3. friend

Now, I am currently using "user relationship" with your module and everything goes fine but... I cannot obviously get the "my buddiylist" avatar block since I am not using the buddylist module.

I am undecided about the relationship modules... Which of the tree horses I should bet on for the long term? Many people assert that "user relationship" is "the" module for the long run but it does not work with your module (or other ones). Decision is crucial since the three modules are not compatible at a data level... and they are core modules for a social networking site like the one I am developing.

Second question. Supposing that I stick with User Relationships, could you tell me how I should do in order to try to adapt your "my buddylist" avatar to work together with UR instead of Buddylist?

Best regards,

Salvatore
