Server and Client type Subscriptions
Server subscriptions are for:


Republishing data
Serve as alternate synchronization partners (This has been deprecated)
Resolving conflicts according to a priority


If your subscription(s) do not require this behavior then a client subscription will work just fine.  This is covered in Subscription Type.

The Merge subscription type can be specified on the Subscription Type page of the New Subscription Wizard or by specifying a value of local (client) or global (server) for the @subscriber_type parameter in sp_addmergesubscription and sp_addmergepullsubscription.  This is covered in Specify a Merge Subscription Type and Conflict Resolution Priority.

I hope this helps.
