Not sure if this is the place for this, but I really think the 'Merge Company' action should be worth 5+ points, not 1. I've generally found it takes more work than updating a company, which is worth 5 points, and can be something simple like fixing the name or phone number. Merging companies seems like something important to the database that should be encouraged.
Also, the merge company system can be difficult to use, especially if there are a lot of similar companies. The URL for every company listing is unique, so if you could just put the url in that would work great.
