Thanks for taking the time to share your experiences around using Picard and MB as a new user with us.
For whatever historical reasons the fact is that Picard and MB forums are as they are.
If you have the time, energy and inclination then the following may be a way that your experiences could be taken into future changes.
Picard: Survey and First Impressions
edit: (All the following is incorrect and outdated)
Without messaging facilities being available currently on MB forums I can point you to release Clàrsach na Bànrighe which I recently edited. With this information you could now, after a series of clicks, email me*. And I could commiserate around the obstacles to quickly learning how to use Picard, acknowledge your restraint in face of these obstacles, and ask you to consider the volunteer nature of the overwhelming majority of Picard/MB contributors, etc. And I'd say how important I think it is that Picard and MB have a far more easily accessible and understandable UI rather soon if the majority of global recorded music from pre-1950 is ever to be included in the MB database.
*Whoops. Not correct. First you'd have to register on musicbrainz.org. Using the same name as you do for the forums is suggested.
