The most important thing to work on is the Data Conflicts in all catagories.
Your Relatives
Followed by you
Managed by you
Managed by your collaborators
The next important is the Tree Conflicts in these 4 areas.
At this point leave the requested merges for awhile
The lease important is the Tree Matches
If you feel the need to work with Requested Merges then be kind enough to immediately go to Tree Conflicts and Data Conflicts and clear (Finish) what you started.
There are a few of you that work in the Merges (Requested & Matches) that never finish (follow through) and you leave a mess for the rest of us that are really trying to clean the tree.
Some of the people that do this I have dropped from my Collaborator list. Then they do not show up for me any more. I am not willing to help anyone who will not participate in their own clean up.. I am speaking of long time members not those new to the tree.
