Reading Simterical's comments, I asked myself, what are the advantages and disadvantages of having Edit Counter as an extension, and not a Toolserver project?

Being part of MediaWiki's (extensions) code allows faster internationlization of messages. Also, there will be no replication lag to take into account. On the other hand, perhaps it may make creation of graphs a little harder, but I'm not sure (since I regularly create several graphs using PHP and GD with my Toolserver account).

What do you think?
